Maybe the original patch is better? Or maybe it should reconfigure the

Andrew,
are you still working on this?
a bunch of tests on my local environment failed because of the reason
James mentioned. for example gcc.target/arm/xor-and.c etc.
I can do, but nobody had any suggestions of a better fix.
It seems that the testsuite is broken different ways with and without
neon. I get it running (and failing) NEON tests on multilibs it should
not, and you get it failing non-NEON tests on toolchains configured to
have NEON by default.
I can apply my original patch, if that works better?
Andrew
