make[1]: *** [arch/mips/kernel/asm-offsets.s] Error 1
make: *** [archprepare] Error 2

The issue is related to

archprepare:
ifdef CONFIG_MIPS32_N32
        @echo '  Checking missing-syscalls for N32'
        $(Q)$(MAKE) $(build)=. missing-syscalls ccflags-y="-mabi=n32"
endif
ifdef CONFIG_MIPS32_O32
        @echo '  Checking missing-syscalls for O32'
        $(Q)$(MAKE) $(build)=. missing-syscalls ccflags-y="-mabi=32"
endif

that if the ifdef'ed code is removed or both if conditions are false
compilation will succeed.
