Extend --with-zstd documentation
The patch that was so far added for documenting --with-zstd is pretty
minimal:
- it refers to undocumented options --with-zstd-include and
--with-zstd-lib;
- it suggests that --with-zstd can be used without an argument;
- it does not clarify how this option applies to cross-compilation.
How about adding the same details as for the --with-isl,
--with-isl-include, --with-isl-lib options, mutatis mutandis? This patch
does that.
