... and rename those determined by toolchain.prf to QMAKE_* (this was
already the case for the newly introduced msvc and icc variables).
this restores the ability for user projects to query the toolchain qt
itself was built with, which is necessary for compatibility checks.
in fact, we may do such validation in toolchain.prf itself at a later
point.

The configure-time detection (cxx11default) isn't enough if the compiler
can be changed. This is especially necessary if Qt is compiled with a
compiler that defaults to >= C++11 (e.g., GCC 6) and then the user
selects a compiler another compiler (e.g., Clang) via -spec option. In
that case, we'd miss adding the -std=c++11 or -std=gnu++11 option to the
command-line, causing the compilation to fail.
As a nice side-effect, even moc without moc_predefs.h will now get the
__cplusplus setting.

this makes it consistent with the determination of the default
include/library paths. this makes sense, as it's possible to switch the
sdk/toolchain after building qt (within reason).
a side effect of this change is that for compilers which emulate other
compilers, both the real and the emulated version are now made
available.
