New bootstrap failure on sparc-sun-solaris2.10

[Art Haas]

The latest set of patches to update the Sparc platform has resulted in a
build failure in stage 1 of this mornings builds:

I'd mailed about bootstrap failures last week, and in those the build
was failing at the stage2/stage three comparison. One question in the
reply to my earlier mail was what version of GNU as/ld I'm, and there
both from binutils-2.21, built on December 15 last year and working fine
all this year:

$ as --version

This assembler was configured for a target of `sparc-sun-solaris2.10'.

I tried to build using the Solaris provided GNU as and Sun ld, but the
build failed when trying to build an 'lto' library. I've unfortunately
removed the build log so I can't copy the error, but it looked to be due
to a path issue where a '.libs' directory did not exist.

Here's the configuration for my last successful GCC build early last
month:

$ gcc -v

Thanks to everyone working on GCC.
