Subject: [PATCH] Add the musl workaround to the libc-compat.h copy

The libc-compat.h kernel header uses glibc specific macros (__GLIBC__ and
__USE_MISC) to solve conflicts with libc provided headers. This patch makes
libc-compat.h work also for musl libc.

Signed-off-by: Baruch Siach <baruch@tkos.co.il>

Upstream status: libc-compat.h is a local copy of a kernel headers. A proper
musl fix must go to the kernel first.
