This is the 3rd iteration of the patch, here are the changes with regard to previous one:
* more precise description of the problem.
* only set r30 in PIC+secureplt case as it seems indeed to be the only case which causes problem. Secureplt without PIC does not need r30.
* don't rely on uclibc being already built: now we check for secure-plt by doing $(CC) --verbose and searching for the ./configure parameters of GCC for "--enable-secureplt".

Yann Sionneau (1):
  powerpc: fix PIE/PIC builds with newer gcc/binutils which use
    secureplt by default
