Fix text relocations in linux-user targets
There is a link hack in linux-user which produces an executable that
looks like PIE, but always has text relocations since all object files
isn't position-independent (compiled without -fpic/-fpie). Dynamic loader
has to do more work to load a binary with text relocations.
The best way to keep this functionality is to build a true PIE without
text relocations.
