	Enabling --host=i386--netbsdelf2.0 causes the generated gcc3 to
	fail to link imap-uw with 'cannot find -lgcc_eh', with either
	the crtstuff or the threads stuff commented out from config.gcc.
	My guess is its causing some other change which is confusing
	buildlink.

	For now I've set recent NetBSD to configure gcc with --enable-threads
	which is enough to get my 1.6U box to build mozilla...
