wget: also depend upon pcre because wget will link against it if its installed.

Looking at wget's source code, it'll use PCRE instead of the OS
provided regcomp/regexec for the --accept and --reject command line
option, if PCRE is available.

$ otool -L /opt/local/bin/wget | grep pcre
      /opt/local/lib/libpcre.1.dylib (compatibility version 2.0.0, current version 2.0.0)
