This is really strange it looks like glibc has wrong syscall number for
getrlimit.

On 32bit ARM I do have in /usr/include/asm-generic/unistd.h

#define __NR_getrlimit 163

While the getrlimit should be 191. It looks like x86-64 syscall
definitions are installed on the system for some strange reason, even
the header says that it's for x86-64.
