Do not build test binaries statically in CI

[matoro]

For the CI runs intended to be testing static binary, only build the main patchelf binary statically, and not the test binaries. This allows us to restore the correct behavior for toolchain builds with PIE enabled by default.

Sounds ok to me in principle

This is clearly not the right solution, as evidenced by it still failing and also upon closer inspection I misread this - -static is not being passed to the test binaries.

Despite running on aarch64 musl I am unable to reliably reproduce this.

You cannot reproduce this when pulling the same container locally?

I was running in a Gentoo aarch64 musl chroot, and yeah it doesn't reproduce there.
