Latest version of pixman has fixed support for compiling the neon assembly files with clang. Older android ndks required disabling the integrated assembler to build them but that workaround is no longer required. This also avoids the bug where older ndks didn't pass -march automatically to external assemblers. See: android/ndk#906 (comment)
GCC does not have syntax unified set explicitly, so pixman has to be able to set it.
Some older clang ndk's integrated assemblers have issues still with the arm64 assembly files. We can just continue disabling the integrated assembler there. The assembly is fine with the integrated assembler on versions r20 and above.
