No. There may be a number of individual components you could use on
such a system, but musl implements, and as a whole makes assumptions
that will necessarily be true on, a POSIX-conforming (and somewhat
Linux-flavored) system. In particular POSIX requires 32-bit int. Even
if you had a 16-bit x86 target with 32-bit int, you would need an arch
target for it matching the ABI and things like how TLS works (but I
wonder if anyone ever even figured out TLS on ELKS).
