Subject: [PATCH] microblaze: Setup proper dependency for optimized lib functions

Optimized library functions are implemented only for little endian.
Setup this dependency via Kconfig.

commit 206d3642d8ee ("arch/microblaze: add choice for endianness and
update Makefile") added an option to setup endianess via Kconfig.
