ldd libc.so.5 - statically compiled, does not need ld-linux, which I
probably did not need to even include in my netpbmt-for-bl2 package.
ls -l libc.so.5 580K
ldd libc.so.6 - needs ld-linux.so.2
ls -l libc.so.6 1.2MB (This is the Slackware 8.1 glibc 2.2.5)
No wonder BL3 switched back to libc5.

ld-linux is included in the static libc5, but not in libc6

The above directory came with SW71 egcs and binutils. I deleted them
both, and gmake, since I now have SW81 gcc, binutils, and make. That did
not fix the problem.

I fixed the problem by looking in my netpbm packages and renaming
/lib/libc.so.5 and libm.so.5 and ld-linux.so.1 (and the files underlying
these symlinks) and
/usr/local/lib/libnetpm* (I had also put it in /lib for no good reason)
The libpng file for libc5 had already been overwritten by the libc6 one.
make -k (for --keep-going) produced files dependent on
libc6 libm6 ld-linux2 libnetpbm and some on libjpeg libpng
