Buildroot has a bug, it left out /usr/lib/crt0.o, crti.o, crtn.o, and libc.so. I have put those in and I did a test compile of udev-151 source, works.
I have re-uploaded the working rootfs here (27.5MB):

here are some uclibc++ patches, it makes C++ apps ~10% smaller and is 1/10th the size of libstdc++
they are good sources for other patches too.

Interesting, I will have a play with aboriginal.
Note that Buildroot does not use uClibc++, it uses the full libstdc++ from gcc.
