PA64 bugfix

[Jeffrey A Law <law@redhat.com>]

The value of DT_LOOS was changed about a year ago in include/elf/common.h
to conform to the latest ELF standard.  Several PA64 specific entries are
defined relative to DT_LOOS.

Thus, gnu-ld would create binaries which would have the new values for
stuff like DT_HP_LOAD_MAP, DT_HP_DLD_FLAGS, etc.  This caused some problems
for HP's dynamic linker as well as gdb.

gdb choked because it used HP's system include files which had the old
values.  Thus, when it tried to read the .dynamic section, gdb didn't know
how to interpret the new values for DT_HP_LOAD_MAP and friends it found.
This caused gdb to fail rather miserably.

This patch defines the PA64 specific .dynamic entries to be relative to the
old value of DT_LOOS (OLD_DT_LOOS).  And not surprisingly gdb and HP's dynamic
linker are much happier now.

Installed.


	* hppa.h (DT_HP_*): Define relative to OLD_DT_LOOS to be
	compatible with HP's tools.
