* hp-psymtab-read.c (do_pxdb): New function. Check whether the
	file needs to be processed by pxdb (an HP debug info massaging
	tool), if so call it.
	(hpread_build_psymtabs): Initialize scan_start to 0 and
	simplify flow of control.

	* somread.c (som_symfile_read): Add call to do_pxdb (),
	in hp-psymtab-read.c.

	* symfile.c (symbol_file_add): Remove ifdef'ed out HPUX specific
	code.
	(symfile_bfd_open): Remove HPUXHPPA ifdef'ed code. Code is now
	in hp-psymtab-read.c.
