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.

1. Adds sha256sum stage to the bash build harness.
2. Adds a third argument to build(), the checksum file name. This is
used where there is more than one checksum file, most notably
in multi-stage compilations.
3. Adds checksum files to all remaining programs.
4. Adds appropriate 3rd argument where needed (coreutils, tcc-musl,
bison).
