/lib /usr/lib /usr/local/lib /usr/X11R6/lib ?

The uclibc static lynx was half the size of the glibc static one.

The output is entirely different.

uclibc dynamic version needs libc.so and libm.so (uclibc version, they are 
symlinked) and the uClibc ld-linux, the glibc version libc.so.6 and 
ld-linux 2 (no libm).
