Actually, I never touched "/etc/ld-musl-ARCH.path" at all.

The way I got musl to work was:

1 - Edited musl's config.mak file to look like this:

    http://paste.pocoo.org/show/546543/

2 - Compiled and installed musl
3 - export PATH=/usr/local/stow/musl/bin:$PATH
3 - export LD_LIBRARY_PATH=/usr/local/stow/musl/lib:$LD_LIBRARY_PATH

From then on, I just used musl-gcc as per the musl FAQ (see the build log below 
for an example).

With #chicken's sjamaan leading the charge, we ripped out a lot of the chicken 
code that was bothering musl, and got quite a bit further in the compile.  The 
below log contains, first, "git diff" of all the changes we made against 
chicken-core, and, second, the compile log as we tried to build chicken:

    http://paste.pocoo.org/show/546219/

As you can see on lines 346+, the compile ended with a complaint about not 
being compiled with -fPIC, and a "bad value" in musl's "crt1.o".

One last thing we tried was to invoke by hand the same musl-gcc command as on 
lines 344 and 345 of the above log, but with -fPIC appended (since, apparently, 
that was the only musl-gcc line in the log that didn't have it for some 
reason), and we got the same error.  Here's teh log of that attempt:

    http://paste.pocoo.org/show/546228/

So we are stuck, for the moment, until we can figure out a way around this 
error, or at least figure out what's causing it.
