John Thomson 62776e4378 mips: boot/compressed: use __NO_FORTIFY 
In the mips CONFIG_SYS_SUPPORTS_ZBOOT kernel, fix the compile error
when using CONFIG_FORTIFY_SOURCE=y

LD      vmlinuz
mipsel-openwrt-linux-musl-ld: arch/mips/boot/compressed/decompress.o: in
function `decompress_kernel':
./include/linux/decompress/mm.h:(.text.decompress_kernel+0x177c):
undefined reference to `warn_slowpath_fmt'

kernel test robot helped identify this as related to fortify. The error
appeared with commit 54d9469bc5 ("fortify: Add run-time WARN for
cross-field memcpy()")
Link: https://lore.kernel.org/r/202209161144.x9xSqNQZ-lkp@intel.com/

Resolve this in the same style as commit cfecea6ead ("lib/string:
Move helper functions out of string.c")
