I also fail to see how && could be unportable. It has been there
since the first UNIX shells in existence.

Another evidence: GNU autoconf generates lots of 'cd foo && ...'
commands for Makefiles. And it's otherwise extremly conservative
when generating shell code (doesn't use functions, uses test
instead of '[').

IMHO it's safe to use this in the Lua Makefiles.
