Certain distributions (e.g. Debian and Ubuntu) have enabled PIE be default in their GCC packaging. This breaks our abuse of GCC as a linker which requires that we pass -Wl,-r, which is incompatible with PIE (since the former implies that we are generating a relocatable object file and the latter an executable). This is a second attempt at D2691. This attempt constrasts with D2691 in that it preserves the "does gcc support -no-pie" flag in settings, allowing this to be reconfigured by `configure` during installation of a binary distribution. Thanks for @rwbarton for drawing attention to this issue.
