[RFA:] don't prune warnings for ld run_dump_test

[Hans-Peter Nilsson]

linking and objcopy
BCC: hp@axis.com

As mentioned in
<http://sourceware.org/ml/binutils/2008-02/msg00114.html>, the
to-be-released dejagnu (and apparently Debian etch packages
named dejagnu-1.4.4.cvs<mumbledate>) prune warnings a bit
heavier than stock dejagnu-1.4.4, causing a ld-cris/warn3 to
fail.  It's pretty dumb to prune warnings when using the
just-compiled ld and objcopy anyway, in particular when we don't
want to lose such messages.  So, let's not apply prune_warnings
for invocations where we can match warnings or errors.

Historically, there has been runtime linkers emitting noisy
hey-this-isn't-exactly-the-expected-libc.so-but-ok-then messages
that may require some pruning to be useful for testing, but
well, IMHO, let's avoid testing linker/objcopy messages on such
systems.

Tested native (Fedora core 4) x86_64-unknown-linux-gnu and
crosses to arm-elf, cris-elf, d10v-elf, h8300-elf,
mmix-knuth-mmixware, frv-elf, i686-elf, m68k-elf, ia64-elf,
m6811-elf, mips-elf, mips64-linux, powerpc-vxworks,
powerpc64-linux, sh-linux, sh-elf, sh-vxworks, sparc-vxworks,
spu-elf and i686-linux: all targets AFACT that have one or more
target-specific run_dump_tests that could theoretically be
affected or representing a general target using one.

Ok to commit?

ld/testsuite:
	* lib/ld-lib.exp (run_dump_test): Don't apply prune_warnings
	for tool invocations where warnings or errors can be matched.
