Amends commit 19b7f854a274812d9c95fc7aaf134a12530c105f, which removed the __PIE__ check because of the GCC version check that was alongside. GCC and Clang define both __PIE__ and __PIC__ for -fPIE, so checking for __PIC__'s presence isn't enough. Drive-by amend the no-PIC #error message to also suggest -DFEATURE_no_direct_extern_access=ON, which is more modern and produces better code for executables too. Because of that, I've also changed the reduce_relocations option to the CMake one, as there is no configure- style equivalent for the modern option.
