Well, what you mean is, we haven't been using an built from the
code in the source tree, but the same code built by some other means.

Meanwhile, the NetBSD-current /usr/src/gnu/usr.bin/ld/rtld/Makefile hack
makes no difference.  It just causes the libc_pic.a in /usr/src/lib/libc
to be used instead of the one in /usr/lib.  The link phase still bombs
out on conflicting definitions for the malloc functions.

So I'm STILL wondering how gets built for the distribution.  The
source you refer to for MIPS and Alpha looks no different than the
source I've got, except it's for ELF instead of a.out.  I doubt if
yours would actually build using its supplied Makefile, any better than
mine does.

However, the NetBSD-current /usr/src/gnu/usr.bin/ld/rtld/Makefile hack
does suggest a possible way to do this.  It uses a "recursive make" to
get the libc source directory in which to find libc_pic.a.  One could
leverage that hack to either build a different version of libc, or to
build just the files from libc that needs.  That Makefile could be
a work in progress, in other words, since the hack it has wouldn't be
required just to get the libc source directory.

Of course, not being a make guru, it would take a learning curve for me
to figure out how to implement either scenario.
