Based on reading over the GCC manual, passing both -m2a and -m2a-nofpu
are redundant, as -m2a-nofpu will provide functional code for both. As
-m2a-nofpu functions with more toolchains and does what is expected,
switch.

-ffixed-r13 is defined commonly for sh2, sh3, sh4.
Move it to arch/sh/config.mk

-ffreestanding is defined at the top Makefile for all architectures.
Do not define it twice for SH2A.

Not all SuperH toolchains support -mno-fdpic. Chances are good that if
the flag doesn't work, it isn't defaulting to the FDPIC ABI, so the flag
isn't needed. So only add it if it is actually supported.

Only the optimization of sh2 had been supported up.
This adds the optimization of sh2a.

Linker needs to use the proper endian/bfd flags even when doing partial linking.
LDFLAGS_u-boot sets linker option which is called it when U-boot is built
(u-boot final).
LDFLAGS sets necessary option by partial linking (use in cmd_link_o_target).
