Backport from cvs 

Fixes:

../sysdeps/unix/sysv/linux/errlist.c:41: weak declaration of `_old_sys_nerr' must precede definition
make[2]: *** [/home/dank/downloads/crosstool-0.24/build/mipsel-unknown-linux-gnu/gcc-3.2.3-glibc-2.2.3/build-glibc/stdio-common/errlist.os] Error 1

as well as breakage on arches where ; is a comment char in asm
