Yes. ld-uClibc.so.0 must be in /lib, but anything else can be put
anywhere in your library path.

Most dynamic uClibc binaries are about the same size as glibc
equivalents. You seem to have found an exception to the rule.

Does ldd give the same output with both binaries? If it does,
the differing gcc versions may make a difference.
