gdb: fix full gdb build for MIPS musl

Currently building full gdb for MIPS musl fails because it's trying to
include <sgidefs.h> which is provided by glibc and uClibc, but not by
musl.

However, the kernel headers provide <asm/sgidefs.h> which has the same
definitions, so we can use that one instead.

Backporting a patch that has been sent upstream. Taken from here:
