[PATCH] trivial fix to provide MULTISUBDIR for libsupc++ makefile

[cgd at sibyte dot com (Chris G. Demetriou)]

I just committed the following (under the 'trivial' rules 8-).
(Alas, I didn't know of libstdc++@gcc.gnu.org when i first sent the
patch a couple of weeks ago.)

Tested by building for a (multilibbed) mips-elf -like target (slightly
different name, and other local configury hacks, but otherwise
mips-elf), and verifying that indeed, the various libsupc++.a
libraries were installed in the right places.

Subject: trivial fix to provide MULTISUBDIR for libsupc++ makefile

When doing a multilibbed build of libstdc++-v3/libsupc++, MULTISUBDIR
needs to be set in the Makefile by libstdc++-v3/configure so that the
libsupc++ library gets installed in the correct place.

This is already done for libstdc++-v3/src.  Obviously, the result of
not doing it for libsupc++ is that all libsupc++ libraries are
installed in the same place ("he who writes last, writes best!" 8-).


The problem was noticed on a mips64-elf-like target, and the fix below
checked on the same.


for libstdc++-v3/ChangeLog:

2001-01-08  Chris Demetriou  <cgd@sibyte.com>

	* configure.in: Place definition of MULTISUBDIR in libsupc++
	Makefiles if appropriate.
	* configure: Regenerate.


FYI: Note that my employer disclaimer is probably no longer valid, due
to the recent acquisition that SiByte underwent.  I've told
assign@gnu.org about it, but this is a trivial patch and so it
shouldn't matter.  (I've submitted no new non-trivial patches since we
were acquired, and I won't do so until the new paperwork is ironed
out, so it's not a big issue, but figured y'all should know.)
Anyway...
