Bug: https://bugs.gentoo.org/898080

Subject: [PATCH 1/1] access_io.c: don't blindly assume outb_p to be available
outb_p is not available in musl libc, the condition using the fuction
was if __i386__ or __x86_64__ was defined. This is not enough, for
example when using musl libc both the conditions are meet but the
function is not available. Hence the addtional check for __GLIBC__ being
defined is added.
