Um, question: is that bionic's libc you're attempting to dlopen?  (It's
an ELF binary, right?  What does readelf -a say about it?  Note that
attemting to dlopen() a linker script may not end well.)

Have you tried to dlopen() one of the other shared libraries that comes
with uClibc just to make sure that the issue is dlopen() and not it
being really confused by that particular library?

I don't understand what you're trying to do there, could you explain?
(You can exec one program from another, if that's what you mean by
boostrap.)

I expect it's possible to link it, whether the result would work
involves knowing more about android than I do.
