Oops.  Yes, Makefile in src/lib/csu/mips needs updating.
The change is simply to un-comment-out the line

	#CFLAGS+=      -I/usr/src/libexec/ld.elf_so

which is already there.  This is fixed in tomorrow's sup.  For now you
can fix it by manually removing the '#" in that line.

The crt0 changes add hooks to support the NetBSD standard ld.elf_so,
which supports dlfn(3) dynamic loading -- e.g., for Perl.  ld.elf_so
needs more mips-specific work too, but this is the first step.
