Subject: [PATCH v2 9/9] nds32: Fix the allmodconfig build. To make sure CONFIG_CPU_LITTLE_ENDIAN is default y

This way we can build kernel with CONFIG_CPU_LITTLE_ENDIAN=y. Build allmodconfig
and allnoconfig are available too. It also fix the endian mismatch issue because
AFLAGS and LDFLAGS is not passed correctly.
