- Subject: [PATCH 4/5] 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.
