gcc-2.95 NEED_DECLARATION_STRSTR

[Jeffrey A Law]

It looks like you've got two unrelated changes in this message.  Note the
libiberty changes at the end of your patch.

I believe the strstr stuff is probably OK and that inclusion of the libiberty
code was a mistake.  Can you confirm?

Thanks,
jeff
