 Pass -no-pie to GCC

 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.
