[U-Boot] [PATCH 1/2 V2] Move libgcc inclusion from common Makefile to platform configs files

This patch moves the libgcc Makefile inclusion from the toplevel Makefile to
the arch_config.mk files. This is in preparation for the ARM architecture to
move away from including libgcc function and only using self-contained U-Boot
functions as done in Linux.
Currently in the next branch all the ARM boards that use the nand are broken due
to the adding of the 64 Bit device size support. In the past we have seen
problems with different toolchains due to EABI, FPU as example.
With this patch and the following one we move away from all these problems and
we will be able to have full control to have a functions embedded into u-boot.
