mesa: fix build on Arm V5 with soft float
Since
80923e8d ("util/format: Add some NEON intrinsics-based
u_format_unpack.") upstream the build fails on Arm platforms which use
the soft-float ABI, such as qemuarmv5:
arm_neon.h:31:2: error: #error "NEON intrinsics not available with the
soft-float ABI. Please use -mfloat-abi=softfp or -mfloat-abi=hard"
Take a patch from upstream to check the ABI being used before trying to
use NEON instructions.
