In theory it should just work.  That's why ld-uClibc.so.conf and 
ld-linux.so.conf have different names by default.  (And uClibc is libc.so.0 
while glibc is libc.so.6)

Only one of them can have the libc.so symlink, but that's a toolchain issue 
trying to build new stuff against it, not a runtime issue.

*shrug* you could, but why?  There isn't a special subdirectory for "binaries 
that link against zlib"...
