[PATCH]: Fix target/6428 for hppa*-hp-hpux*

This patch adds a warning when linking with -pg or -p without -static.
HP only provides libraries for profiling in archive format.  On the
32-bit port, shared library dependences are usually hardcoded.  As
a result, you can end up with a wonderful mix of libc/libm routines,
some from non-profiling libraries and some from profiling libraries.
This is particularly a problem using the g++ driver which defaults
to linking with libgcc_s.

I also moved the location for emitting the -L locations for the profiling
libraries as I noted that otherwise the profiling version of libm
under hpux10.20 wouldn't be selected.

Three tests that use -p or -pg have been updated to add -static to
the test options under hppa*-*-hpux*.

Installed on trunk.

	PR target/6428
	* pa-hpux10.h (LINK_SPEC, LIB_SPEC): Move -L options for profiling
	directories from LIB_SPEC to LINK_SPEC.  Emit warning if `-p' or `-pg'
	option is used without `-static'.
	* pa-hpux11.h (LINK_SPEC, LIB_SPEC): Likewise.
	* pa64-hpux.h (LINK_SPEC, LIB_SPEC): Likewise.

	* g++.old-deja/g++.law/profile1.C (dg-options): Add -static to options
	for hppa*-hp-hpux*.
	* gcc.dg/20021014-1.c (dg-options): Likewise.
	* gcc.dg/nest.c (dg-options): Likewise.
