(that's this system, when I'm running send-pr, the problem happened on...)

>Description:
	Attempt to cross compile on an alpha, producing i386.
	This used to (almost) work - there's a c++ compiler error
	(produces bad assembly code (PR bin/14489) - or was - I was
	attempting to get that far gain to possibly investigate the
	cause, if the problem remains)

	This is the first time I have attempted this since autoconf
	was added to the tools used ...

	The attempt ends ...

configure: error: *** Gdb does not support host alpha-unknown-netbsd1.5R
Configure in /usr/obj/tools/toolchain/build/gdb failed, exiting

	I have the full (600Kb) make log (mostly from a cleandir that
	preceded the build) if anyone needs more that.

>How-To-Repeat:
	Get on a NetBSD alpha ...

	In /etc/mk.conf put

MKOBJ=yes
MKOBJDIRS=yes
OBJMACHINE=yes
#
BSDSRCDIR=/usr/src
BSDOBJDIR=/usr/obj
#
KERNSRCDIR=/usr/src/sys
KERNOBJDIR=/usr/obj/sys
#
# DISTDIR=/home/distfiles
WRKOBJDIR=/usr/obj/pkgsrc

	(and some other stuff that relates only to pkgsrc).

	Then run:

(cd /usr/src; /usr/tools/bin/nbmake cleandir; ./build.sh -u -m i386 -T /usr/tools -O /usr/obj -D /home/trees/i386 -R /home/snapshots/i386 ) 2>&1 | Mail -s Build kre &

	The relevant part of that, is ..

	./build.sh -u -m i386 -T /usr/tools -O /usr/obj \
		-D /home/trees/i386 -R /home/snapshots/i386

>Fix:
	I guess, don't attemmt to autoconf gdb when cross-compiling
	(at lest when it isn't supported).
