MIPS: zboot: Fix the build with XZ compression on older GCC versions
Some older GCC version (at least 4.6) emits calls to __bswapsi2() when
building the XZ decompressor. The link of the compressed image then
fails with the following error:
arch/mips/boot/compressed/decompress.o: In function '__fswab32':
include/uapi/linux/swab.h:60: undefined reference to '__bswapsi2'
Add bswapsi.o to the link to fix the build with these versions.
