Make it a choice menu which offers the 3 C libraries we know about: glibc,
uClibc and musl. While at it, make it possible for the external toolchain libc
to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages
to conditionally include specific CFLAGS (e.g: iproute2).
Because USE_GLIBC et al. can now be selected by external toolchains, we need to
restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN.
While at it, make musl the default C library for external toolchain to match
the internal toolchain.

Specify the libc type used by the external toolchain. The given value
is passed as -m flag to all gcc and g++ invocations. This is mainly
intended for multilib toolchains which support glibc and uclibc at
the same time. If no value is specified, no -m flag is passed.
