branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
As reported by Toolchain-builder project [1], the system doesn't
boot when PIC/PIE is enabled for glibc based toolchain (the init
process hang).
Also, hardening features may not be wanted or possible for such
slow soft-core cpus [2].
Like for NiosII, disable BR2_PIC_PIE.
