Subject: [PATCH] avoid neon for targets which don't support it
The sh-mem-random.c test app tries to use neon loads and stores to
test 64-bit float copies when building for ARM. Allow it to do so if
possible, but fallback to C when building for ARM targets which don't
support neon.

/* On arm32, many compilers generate a 64-bit float move
using two 32 bit integer registers, which completely
defeats this test. Hence force a 64-bit NEON load and
