I went ahead and applied these two patches.

Some of the chez-* packages currently fail due to some TeX Live issue
unfortunately, but at least ‘chez-fmt’ and ‘chez-scmutils’ build fine
with these changes.

It would still be interesting to link dynamically (instead of
statically) against libz and liblz4 as a followup.

Thanks,
Ludo’.
