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.

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.

Clean up ltcg.prf with variables, including a new static mode By using the special "ar" and "ranlib" tools, the symbol table is made visible, so we don't need fat LTO binaries. Since we need to store the new tool names, we may as well clean up ltcg.prf with variable names for the fat mode too.
