[Buildroot] [PATCH] Config.in: disable PIC/PIE for microblaze

[Romain Naour <romain.naour@gmail.com>]

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.
