[RFC PATCH 3/5] musl: set compatibility a bit more flexible

[Denys Dmytriyenko <denis@denix.org>]

From: Denys Dmytriyenko <denys@konsulko.com>

Like musl Linux config, baremetal also uses musl as a libc, but
it has a different host triplet set. Hence adjust COMPATIBLE_HOST
to accomodate this use case by checking that musl is a preferred
provider of libc.

[YOCTO #15982]
