Cygwin: fix mknod (64-bit only)
The current definition of mknod in syscalls.cc has a third argument of
type __dev16_t instead of dev_t. Fix this on 64-bit Cygwin by making
the existing mknod 32-bit only and then exporting mknod as an alias
for mknod32. (No fix is needed on 32-bit because mknod is redirected
to mknod32 via NEW_FUNCTIONS in Makefile.am.)
