The following build error is seen if CONFIG_32BIT is undefined,
CONFIG_64BIT is defined, and CONFIG_MIPS32_O32 is undefined.

asm/syscall.h: In function 'mips_get_syscall_arg':
arch/mips/include/asm/syscall.h:32:16: error: unused variable 'usp' [-Werror=unused-variable]
cc1: all warnings being treated as errors
