This is a patch for uClibc/libc/sysdeps/linux/mips/sys/procfs.h pulled
from glibc CVS.

This fixes gdb with threaded application (with glibc environment).
Although debugging threaded programs seems not working on uClibc/mips
yet, this patch will be required when it becomes working.

This patch can be applied to any version of uClibc (including current
CVS).
