Bootstrap error in stage1 libgcc2.a on mips-sgi-irix6.2

[Billinghurst, David (CRTS)]

On irix6.5, 20000403 snapshot,  this patch gets me past that error, but soon
after I get

for name in _eh; \
do \
  echo ${name}; \
  ./xgcc -B/exd4/billingd/tmp/egcs-20000403/mips-sgi-irix6.5/bin/ -B./

  if [ $? -eq 0 ] ; then true; else exit 1; fi; \

done
