Subject: [PATCH 12/12] static-pie

in gcc-8 -static means static non-pie, even if -pie or -static-pie
are specified, -static-pie can be used to build static pie.

in musl toolchains -static -pie always meant static pie, so this
patch fixes the link specs accordingly, the new -static-pie is just
an alias to -static -pie.
