Well, better than documenting (suggested by Philip), an helpful error
message would be great.

Eg, right after determining which lzma binary to use, test if it can
actually be executed (not sure if -x is enough for this), and if not,
exit with a message like:

> Lzmadec cannot be executed, strange. Possible reasons for this:

Unfortunately, I don't undestand install-tl enough to find a good place
to put this test and suggest a patch.
