On ARM at least, I don't think so. From what I see, the -pie ld option
without the -fPIC/-fPIE compiler option alone builds a .rel.syn table
that contains all necessary fixes to mve the code anywhere.

However:

I second that. More precisely, I'd suggest to wait for ELF relocation to
succeed on arm296ejs before considering any other ARM, then any other arch.
