FYI: README-hacking: note that gperf is required

[Jim Meyering]

Cc'ing gnulib, because I doubt that Coreutils is the only
package that requires this sort of change.  This build-from-source
dependency (a few months old, actually) comes solely from the use of
gnulib's linebreak module, which requires the iconv_open module,
which uses Gperf.

        * README-hacking: List Gperf as a build-requirement, too.
