Subject: [PATCH] Don't call uname or getrlimit in libpthread init function
* sysdeps/unix/sysv/linux/i386/Versions: Export __uname under
GLIBC_PRIVATE.
* nptl/Versions: Export __getrlimit under GLIBC_PRIVATE.
* sysdeps/unix/sysv/linux/i386/smp.h: Call __uname instead of uname.
* nptl/nptl-init.c: Call __getrlimit instead of getrlimit.
