22e9ff9c16 mkspecs: Allow specifying a CROSS_COMPILE for mac/clang targets
This allows distinguishing between these tools and tools for the host,
when cross compiling.

While mac tools normally only are available on macOS, there are third
party efforts to port them to other platforms. In these cases, it
might be useful to use a prefix (either some sort of triplet prefix,
or an absolute path) to distinguish between the host build platform
compilers/tools and the ones for the cross target.

The use of this variable matches the one used in a lot of other
mkspecs, and shouldn't cause any issues for those who aren't setting
it.

4684c1afe5 Add detection of C++14 and C++1z compiler features
[ChangeLog][General Improvements] Qt's buildsystem now detects whether
the compiler supports C++14 and experimental support for C++1z. If the
compiler supports it, then Qt is automatically compiled using that
support.
\
This does not apply to user applications built using qmake: those are
still built with C++11 support only. To enable support for C++14 in your
application, add to your .pro file: CONFIG += c++14 (similarly for
C++1z).

ff44440651 Make CONFIG += c++11 by default not disable GNU extensions
Prefer -std=gnu++11 unless strict_c++11 is defined. You can enable
strict C++11/C++14 mode by using
   CONFIG += strict_c++

That is enabled for Qt's own code, so we we don't accidentally use GNU
extensions in portable code.

There's no support for strict C++98 mode (that is, the -ansi option).

[ChangeLog][qmake] By default, GNU extensions are now enabled with
Clang, GCC and ICC even in C++11 and C++14 modes. To disable the GNU
extensions, add to your .pro file: CONFIG += strict_c++.

2b9a793dcd Set the _C variants of QMAKE_LINK and QMAKE_LINK_SHLIB in clang.conf.
While it does not look like the clang-based mkspecs had any problems so
far with not having QMAKE_LINK_C and QMAKE_LINK_C_SHLIB defined, it
makes sense to set them to $$QMAKE_CC just like the GCC-based ones so
CONFIG=use_c_linker works as expected.

1bd27f24fb Add link-time optimization support for Clang, GCC and ICC
GCC currently requires fat object files for static libraries, since the
linker would otherwise not load the .o file from the archive at all and
the linking would fail with a lot of undefined references. Clang on
Linux also needs this, but it has no equivalent flag, so enabling LTCG
for Clang on static libraries will result in linker error.

This commit does not add support for enabling it in configure. It can be
enabled on a per-project basis by doing CONFIG += ltcg or by passing
-config ltcg to qmake's command-line.

5fcf441392 Fix '=' alignment and replace tabs in *.conf (whitespace only change)
Replace all tabs with proper space characters and consistently align
the '=' characters. The default alignment for the '=' of 25 characters
has been left as is to get a minimal diff. Lines with the '=' further
to the right and those belonging to 'proper code (TM)' have not been
touched.

The work was mostly done using the following python script (might
come in handy again...):

import sys, re
indent_eq = 25 + 0*4 # 25 characters was the most widely used indentation for the '=' character
p = re.compile(r'(\w+)[ \t]*([\-\+]?)(=$|= )[ \t]*(.*$)')

for fn in sys.argv[1:]:
    with open(fn, 'r+') as f:
        lines = []
        nl_count = 0
        continuity_indent = None
        for l in f:
            m = p.match(l)
            nl = l
            if m:
                n_spaces = max(m.start(3), indent_eq - 1) - len(m.group(2)) - len(m.group(1))
                if m.group(2) and m.start(2) >= indent_eq-1 and m.start(2) % 4 == 0:
                    n_spaces -= 1 # left-shift '+=' by one if the '+' is aligned to a multiple of 4
                n_spaces = max(1, n_spaces) # we want at least one space before '='/'+='
                nl = m.group(1) + ' '*n_spaces + ''.join(m.group(2,3,4)) + '\n'
                continuity_indent = nl.find('= ') + 2 if l[-2] == '\\' else None # remember indent on '\\$'
            elif continuity_indent:
                nl = ' '*continuity_indent + l.lstrip()

            if l != nl:

fff5a8f9c9 make qmakespecs announce the compiler family
on the way to eliminate scoping based on the spec.

gcc and msvc go as such into CONFIG, the other ones get the vendor
prefixed, as most are mostly unknown and thus likely to clash with
users' flags.

6a51062e99 Move the SSE2/AVX/Neon/etc. flags into the compiler mkspecs
This allows us to have different flags for the compilers for
supporting the same feature. For example, the official flag in GCC to
support AVX2 is -mavx2, but ICC does not support it (yet), requiring
-march=core-avx2 or -xCORE-AVX2. That flag, instead, enables support
for all the features that the "Core-AVX2" processor (codename Haswell)
will support. And clearly, the MSVC flags are different.

bf84d1a1fe configure: Auto-detect and enable C++11 support if available
Enabling support for C++11 adds CONFIG+=c++11 to the Qt build. Projects
using Qt can check for C++11 support using contains(QT_CONFIG, c++11) in
their .pr[iof] files.

The QMAKE_CXXFLAGS_CXX11 and QMAKE_LFLAGS_CXX11 qmake varibles contain
any arguments the compiler needs to enable C++11. CONFIG+=c++11 adds
these arguments to the build.

Support for clang, g++, and the Intel C++ Compiler for Linux are
included in this commit.
