>Description:
	When typing 'make instbin' in /usr/src/distrib/miniroot, you will
eventually see something like:
247: libhack.o: Definition of symbol `__endhtent' (multiply defined)
248: libhack.o: Definition of symbol `__gethtent' (multiply defined)
249: libhack.o: Definition of symbol `__gethtbyname' (multiply defined)
250: libhack.o: Definition of symbol `_gethostbyname' (multiply defined)
251: libhack.o: Definition of symbol `__gethtbyaddr' (multiply defined)
252: libhack.o: Definition of symbol `_gethostbyaddr' (multiply defined)
253: libhack.o: Definition of symbol `__sethtent' (multiply defined)


>How-To-Repeat:
>Fix:

Since it looks to be caused by a reference to gethostbyname2() somewhere
(probably from within libc), a solution is to add this functionality to
/usr/src/distrib/utils/libhack/gethost.c. The patch below does this.
