#62768: mpich: port uses hwloc, but doesn't declare a dependency on it

---------------------+----------------------
 This port explicitly links against hwloc, via configure argument `-with-
 hwloc-prefix=${prefix}`. But the port file doesn't declare a lib
 dependency on hwloc.

 Output from `otool`, showing that mpich binaries are linked against hwloc:
