Include libiberty.h in files that use htab_create()

Hi Geoff,

Upon further searching I uncovered this patch:

  http://sources.redhat.com/ml/binutils/2002-06/msg00158.html

  2002-06-06  Geoffrey Keating  <geoffk@redhat.com>

	* merge.c (merge_strings): Use htab_create_alloc with calloc, not
	htab_alloc.
	* elf-strtab.c (_bfd_elf_strtab_finalize): Likewise.

Is this the one you mean ?  If so why do you say that it is
incompatible ?  I tried applying it and the BFD library appears to
build just fine either with the binutils version of hashtab.h or the
gcc version of it.

Cheers
        Nick
