ports/99284: openoffice.org-2.0 fails on current because of the addition of gethostbyname_r to libc

[NAKAJI Hiroyuki]

I found another build error; the diff I sent for gethostbyname_r() is
not sufficient. So I give up this PR. The problem seems to be in
libpthread.

The error occurs on recent current like this.

Checking DLL ../../../unxfbsdi.pro/lib/check_libmozabdrv2.so ...Fatal error 'Spinlock called when not threaded.' at line 91 in file /usr/src/lib/libpthread/thread/thr_spinlock.c (errno = 2)

Stop in /usr/ports/editors/openoffice.org-2.0.

My thr_spinlock.c is Rev. 1.24.
