This reverts commit 2d4da30fde.
This Gnulib update was causing failures related to timezones in
stime.c. I tried to fix it by adopting the time_rz module from gnulib
but that then caused other failures. We can try again later.
* lib/iconv_open-osf.h:
* lib/iconv_open-aix.h:
* lib/iconv_open-hpux.h:
* lib/iconv_open-irix.h: Add to git. Should remove build-time dep on
gperf; we'll see if this causes problems.
