		*** BUILD ABORTED ***
	
	This is because our libc's soft float functions (lib/libc/softfloat)
	are conflicting with libgcc's soft float functions.  There lacks a way
	to build the libgcc's soft float functions conditionally, which seems
	to need a hack in our gcc/libgcc build process.
	
	A work around by M L Riechers is
		http://mail-index.netbsd.org/current-users/2004/01/17/0005.html
	
	This tweaks /mnt/mnt/usr/local/src/usr/src/gnu/lib/libgcc3/powerpc.mk
	to not build conflicting functions in libgcc.
>How-To-Repeat:
	% cd /usr/src
