[PATCH] Fix pr87156 ICE building libstdc++ for mips64

[Paul Hua]

Hi:

The bug pr87156 make MIPS target bootstrap fail a month ago. The
attached patch that posted under bugzilla by Jan Hubicka fixed the
bug.
Bootstrapped and reg-tested on mips64el-linux-gnu and x86_64-pc-linux-gnu.
Considering that Jan not very active, Is it OK for commits the patch
under Jan Hubicka behalf ?

Thanks

Paul Hua
