I just looked on PPC-32, uClibc-0.9.30.2. The total size of code is
128 bytes, plus one long; which is a grand total of 132 bytes (if my
maths are not too busted, and I did not miss any symbol).

Also, looking at [0] (glibc-centric, but seems appropriate for uClibc as
well), it seems that those two files are indeed really necessary.

So, two questions:
- is it at all possible to generate a proper uClibc-based toolchain without
  those two files?
- even so, are those 132 bytes really worth an option in the menuconfig?
