[Buildroot] [git commit branch/2021.02.x] Config.in: disable PIC/PIE for microblaze

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=65f936159cabb2ed2efe1cb413c126e2e58cd522
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

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.
