[Bug bootstrap/37279] New: bootstrap on sparc fails on genattrtab

["laurent at guerby dot net" <gcc-bugzilla at gcc dot gnu dot org>]

Last successful sparc testresult (sun or linux) is from 06Aug2008:

http://gcc.gnu.org/ml/gcc-testresults/2008-08/msg00636.html
"trunk revision 138734"

Whereas there were plenty of results before.

At trunk revision 139756 on sparc-unknown-linux-gnu I get during stage2:

build/genconfig ../../trunk/gcc/config/sparc/sparc.md \
          insn-conditions.md > tmp-config.h
/bin/sh ../../trunk/gcc/../move-if-change tmp-config.h insn-config.h
echo timestamp > s-config

If I try to debug:
