patch

Hi,				     

It seems that clang 5.x has implemented the .altmacro directive and now pixman
enables neon and simd on armv6. 				      
clang integrated assembler doesn't understand .func / .endfunc and other
directives used by simd/neon code in pixman and our linker is too old
to link some binaries. We need to disable the integrated assembler and use
binutils on armv6. neon is an armv7 feature so we need to disable it for armv6.
See attached patch, it fixes the build on armv6.

Thanks in advance.
