Rebuild musl libc after building tcc-musl, and then rebuild tcc-musl

This fixes an issue with printf not printing doubles or floats
correctly, and probably other subtle issues.

tcc-musl also uses floats extensively, so rebuild it as well, to fix
some other potential issues.

Update checksums for all resulting binaries which have now changed.

 We recompile `tcc` against musl. This is a two stage process. First we build
 tcc-0.9.27 that itself links to Mes C library but produces binaries linked to
 musl. Then we recompile newly produced tcc with itself. Interestingly,
-tcc-0.9.27 linked against musl is self hosting.
+tcc-0.9.27 linked against musl is self hosting.  Finally, we rebuild musl once more
