RFE: alternate universal build of libiconv

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

Attached is an alternate build mechanism for libiconv which,
hopefully, is a little easier to maintain.

I'd like to use this, but on Tiger / PowerPC it says:

--->  Verifying checksum(s) for libiconv
--->  Extracting libiconv
--->  Applying patches to libiconv
--->  Configuring libiconv

Attaches is another try using the merger_host variable.

[ryandesign (Ryan Carsten Schmidt)]

This is affecting cairo as well, so I think it's something that should be handled by muniversal and not the individual portfiles, so I filed #18214.

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

With r46000, there is no longer a need to set merger_host.
The new Portfile.diff reflects this.

[ryandesign (Ryan Carsten Schmidt)]

Committed in r46078, thanks.
