toolchain: Rework external toolchain libc selection
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. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

help
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.
