FYI: armv5 tried to use the thumb2 JIT when passed -Xcomp

armv5 tried to use the thumb2 JIT when passed -Xcomp
This causes a lot of failures on the armv5 armel buildbot for all jtreg tests using the -Xcomp flag.
this patch fix:

I will push this patch to icedtea6 head and icedtea6-1.11 release branch.
