[uClibc] Link error with ARM tool chain

[Hongbo Rong]

I just start to know uclibc, and really have no much to say. But I got
into some linking problems days ago, and the solution maybe helps in your
situation.  It seems that some header files correspoinding to libc are not included
correctly. You may try to add -L.../uclibc/../include before -lc.

Good luck.
