ARM Neon Tests Failing on non-Neon Target

Hi,

I am looking at the arm-rtems test results for the
trunk and noticing that most failures appear to be
for neon tests.

[joel@rtbf64a gcc]$ grep ^FAIL gcc.log.sent  | wc -l
2203
[joel@rtbf64a gcc]$ grep ^FAIL gcc.log.sent | grep /neon/  | wc -l
1986

http://gcc.gnu.org/ml/gcc-testresults/2010-04/msg02780.html

I see that there is an arm_neon_ok check in lib/target-supports.exp
but it only checks that neon code compiles.  It will compile but the
target can't run it.

Any ideas other than a "no_neon" setting in the board file?
