Force -fPIE on ELF if Qt is built with reduced relocations
Put in qconfig.h whether qt is compiled with reduced relocations.
When using -Bsymbolic-functions (enabled by default on Qt)
but not -fPIE, the comparison of the function pointers fail
because the addresses are different in Qt, and in the executable.
Hence we now enable -fPIE by default on qmake, and force a compilation
error when it is not enabled and built with reduced relocations.
