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.
