Description
If configure is given the platform spec 'macx-llvm', simd components (e.g. qdrawhelper_sse2) aren't compiled leading to a link failure of libQ5Gui.dylib:
Undefined symbols for architecture x86_64:

Problem is in mkspecs/features/simd.prf which fails to match the project spec and doesn't generate the necessary compiler directives for SSE2_SOURCES, etc.
