[MIPS] Remove '-mno-explicit-relocs' option when CONFIG_BUILD_ELF64
This patch removes '-mno-explicit-relocs' usage when
CONFIG_BUILD_ELF64 is set since this option was only required
with the old hack to truncate addresses at the assembly level
where "-mabi=64 -Wa,-mabi=32" was used.
This should yield a small code size improvement for inline
assembly, where the R constraint is used.
The idea is coming from Maciej <macro@linux-mips.org>.
