Peter Mazinger writes:
The attached patch generalizes the use of PIE (all archs are brought in
sync that use/mention it: x86/ppc/frv) and makes use of it building the
target utils.
Tested on x86, ppc should be tested, frv uses -fPIE at one location, but
at another place -fpie, I don't know which is correct (could be both) and
misses the target addition in Config.in.
The test for ppc (requires the earlier sent crt-correction patch to work
correctly):
enable UCLIBC_PIE_SUPPORT, build uClibc and utils, check:
file ./utils/ldd, it should show shared object (instead of executable)
