build: clang support
This works with at least one version of clang
that existed at one moment in time.
No guarantees about clangs past or future.
To try:
CC=clang all.bash
It does not work with the Xcode clang,
because that clang fails at printing a useful answer
to:
clang -print-libgcc-file-name
The clang that works prints a full path name for
that command, not just "libgcc.a".
Fixes #4713.
