Just reading some of my backmail here and I want to clarify a point. 
That file was taken from a gentoo *glibc* system not musl.  On the 
stage3 tarballs I push out we have:

# file /usr/lib/libc.so
/usr/lib/libc.so: ELF 64-bit LSB shared object, x86-64, version 1 
(SYSV), dynamically linked, stripped

Admittedly other .so's in /usr/lib use similar ld scripts, this is not 
the case for libc.so on gentoo musl stages.

I know this is a bit of an aside, but I didn't want readers of this list 
to be mislead.
