The typedef name intN_t designates a signed integer type with width N,
no padding bits, and a two's complement representation. Thus, int8_t
denotes such a signed integer type with a width of exactly 8 bit

To be honest, i think if NetBSD breaks the standard then it can also
carry QEMU patches in its ports collection. Regardless, from my point
of view the last option is the only one viable (not that i will commit
the patch once presented, but i might consider it)
