[OE-core] [PATCH 00/13] Add musl to OE-Core

[Khem Raj]

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.

v2: Address review feedback

  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
