4e9dc46dea0ef8cf15c567fa863796bb23099d0b re-enabled hardening for Musl,
which is good.
Though static builds for ARM fail in various ways
- cross armv7l static does not build
- cross aarch64 static produces segfaulting dynamically linked binaries
- native aarch64 static also produces segfaulting dynamically linked binaries
It seems that for native x86_64-linux, static builds are fine though.
This works around the issue by removing PIE from the hardening flags,
keeping all other hardening flags. This is an improvement (I think) from
before 4e9dc46d.
Fixes#114953
