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). CC: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
