Config.in: add BR2_PIC_PIE_ARCH_SUPPORTS hidden option

Browse Source 
The nios2 architecture is already excluded from PIC/PIE due to issues,
and we're going to also exclude Microblaze, so let's introduce a
BR2_PIC_PIE_ARCH_SUPPORTS hidden boolean to facilitate adding this new
architecture exclusion.
