Joerg Bornemann 943340222e CMake: Generate qdevice.pri when cross-building
This adds the CMake equivalent to the classical -device-option key=value
configure argument:
-DQT_QMAKE_DEVICE_OPTIONS=key1=value1[;keyN=valueN]
The keys and values get dumped verbatim into qdevice.pri.

This patch also ports the machineTuple configure test. Its result is
written into qdevice.pri as value for the GCC_MACHINE_DUMP variable.

# By default we don't want to allow mixing compilers for building different repositories, so we
# embed the initially chosen compilers into the toolchain.
# This is because on Windows compilers aren't easily mixed.
# We want to avoid that qtbase is built using cl.exe for example, and then for another repo
# gcc is picked up from %PATH%.
# The same goes when using a custom compiler on other platforms, such as ICC.
#
# There are a few exceptions though.
#
# When crosscompiling using Boot2Qt, the environment setup shell script sets up the CXX env var,
# which is used by CMake to determine the initial compiler that should be used.
# Unfortunately, the CXX env var contains not only the compiler name, but also a few required
# arch-specific compiler flags. This means that when building qtsvg, if the Qt created toolchain
# file sets the CMAKE_CXX_COMPILER variable, the CXX env var is ignored and thus the extra
# arch specific compiler flags are not picked up anymore, leading to a configuration failure.
#
# To avoid this issue, disable automatic embedding of the compilers into the qt toolchain when
# cross compiling. This is merely a heuristic, becacuse we don't have enough data to decide
# when to do it or not.
# For example on Linux one might want to allow mixing of clang and gcc (maybe).
#
# To allow such use cases when the default is wrong, one can provide a flag to explicitly opt-in
# or opt-out of the compiler embedding into the Qt toolchain.
#
# Passing -DQT_EMBED_TOOLCHAIN_COMPILER=ON will force embedding of the compilers.
# Passing -DQT_EMBED_TOOLCHAIN_COMPILER=OFF will disable embedding of the compilers.
