[Mesa-dev] [PATCH] configure: Add a condition for compiling for ARM.

[Eric Anholt]

This will let VC4 do some ARM-specific optimizations while still having
the simulator build on x86.
---

I'm finishing building the series for doing NEON optimizations today,
but I wanted to get this out there for review since it touches shared
code.

I didn't replicate the 'case "$host_os"' for this check.  Do we need
that?  I'm planning on using gcc intrinsics for arm asm code, so it
doesn't seem host os dependent.
