Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS 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).

sh: only add -mno-fdpic if the compiler supports it 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.
