The setsign() macro gets called with an integer argument in a
few places, leading to a harmless warning in gcc-7:
arch/x86/math-emu/reg_add_sub.c: In function 'FPU_add':
arch/x86/math-emu/reg_add_sub.c:80:48: error: ?: using integer constants in boolean context [-Werror=int-in-bool-context]
This turns the integer into a boolean expression by comparing it
to zero.
