Touching ports.h fails to rebuild sockets.o and posix.o. Both sockets.c and posix.c include fports.h, which includes ports.h, so this rebuild should be automatic.
Andy pointed out that this probably has to do with the special handling
of sockets.c and posix.c:
* Both are conditionally included depending on configuration.
* Their object files don't include "libguile_2.0_la" in the names.
