[Patch Darwin/PR49992 1/2] remove ranlib special-casing from the darwin port.

[Iain Sandoe <developer@sandoe-acoustics.co.uk>]

As per the PR audit trail, there is no reason to retain this special- 
casing for Darwin.
  (given that current GCC is not build-able using Darwin toolsets of  
the vintage that required the case).

Mike has OK'd this off-list - but, since Ralf commented on the  
previous version, I'd like to give him the opportunity to comment here.
OK for trunk?
