 libiconv's configure script pulls in gawk (which isn't set as a
 dependency).

 I discoved this when doing an uninstall/reinstall of libiconv, as gawk
 didn't run when libiconv had been uninstalled, yet libiconv wanted to run
 gawk.

 This can probably be fixed similarly to how we handle it with apr (set an
 environment variable so that the configure script uses 'awk' instead of
 'gawk')
