The CMake compiler test functions are built atop CMake's try_compile()
function. try_compile() ignores configuration specific link flags in
favor of the generic linker flag variable (CMAKE_EXE_LINKER_FLAGS is
used instead of CMAKE_EXE_LINKER_FLAGS_<CONFIG>). This patch applies
the flags cached in AOM_EXE_LINKER_FLAGS to CMAKE_EXE_LINKER_FLAGS
during C and C++ compiler tests.
