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.
