In 32-bit compat mode, however, two syscall implementations that COMPAT_FREEBSD32 assumes will be there are missing. Provide implementations for these: ofreebsd32_sigreturn (which we'll never encounter, so implement it as nosys as is done in kern_sig.c) and ofreebsd32_getpagesize, where we'll always return 4096 since that's the only PAGE_SIZE we support, similar to how the ia32 implementation does things.
