ARMv7 SIMD: Fix clang compatibility

By design, clang only supports Unified Assembler Language (and not
pre-UAL syntax):
https://llvm.org/bugs/show_bug.cgi?id=23507
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0473c/BABJIHGJ.html

Thus, clang only supports the strbeq instruction and not streqb, but
unfortunately some versions of GCC only support streqb.  Go, go
Gadget #ifdef...

Based on https://github.com/mattsarett/libjpeg-turbo/commit/a82e63aac63f8fa3
