Subject: sparc32/sysdep.h and gcc-3.1

Hi,

When building glibc-2.2.5 for sparc with gcc-3.1 I get a build error

Apparently "cpp0 -lang-asm" now leaves spaces around ## in place, if the token
on the left or right of it is a lone dot (not a valid C identifier). Hard to
say that it's a bug in the gcc-3.1 cpp, because -lang-asm is a gcc extension.
The fix is just to remove the spaces.
