Add musl to OE-Core

This is a mimimal set of changes brought in from meta-musl to OE-Core, with this set one can build core-image-minimal using musl by setting

TCLIBC=musl

for all supported architectures, eventually we will bring more changes to other packages which will enable more complex image builds and eventually world.

Khem Raj (13):
gcc: Add support for building musl configuration
autoconf: Add musl support
gdb: Fix build with musl
mtd-utils: Backport and create patches to support musl
squashfs-tools: Define FNM_EXTMATCH if not defined
mtools: Use proper glibc override to add glibc packages to
recommendations
musl: Add recipe
sysvinit: Fix build with musl
gettext: Delete libintl.h and charset.alias
busybox: Add config for musl
openssl: Add musl configuration support
libpam: Fix build with musl
attr: Add patch to account for use of internal glibc header
