build: add -D_NETBSD_SOURCE for NetBSD

memrchr() signature is not exposed by default for NetBSD.  If one does
not add -D_NETBSD_SOURCE, the compiler uses its own signature for
memrchr() that returns a 32-bit integer, leading to misbehaviour in some
situations.  Defining _BSD_SOURCE doesn't work, so we define
_NETBSD_SOURCE.
