what is with the objs subdir ? am i misreading or is this only for 1 file so
the indirection is pointless ? also silently ignoring errors from that seems
like a really bad idea.
i thought $* was for implicit rules which this is not. so really you're
writing the output to "objs/.o".

use $(...) rather than ${...}
any reason you don't use $< here ?
