fltk-devel update, fix universal build

[jarno.rajahalme@…]

This update addresses several issues:

1. Updated to the newest fltk 1.3 weekly snapshot (1.3.x-r8472), that contains important fixes for OSX builds:

• Given proper configure args fltk actually builds as universal, and fltk-config no longer reports any -arch flags. See ​http://fltk.org/newsgroups.php?s10749+gfltk.development+v10762+T0

• This, and an earlier fix in fltk header files (to not include OSX system headers, e.g. Objective-C headers, when compiling an application, see ​http://fltk.org/newsgroups.php?s10369+gfltk.development+v10385+T0) allows FLTK Applications to be compiled with non-Apple GCC versions (such as the various MacPorts toolchains).

As an example, the new release of GNU Octave uses FLTK. These changes allow Octave to be built with gcc-mp-4.5, even though FLTK itself must be built with Apple GCC 4.2.

2. Updated the Portfile to pass arch flags only via --with-archflags, i.e. the same flags are removed from CFLAGS, etc. Without this change fltk-config still reports the archflags, which makes it hard to build e.g. an 64-bit app using universal fltk dylib.

3. Make universal variant the default, so other ports can depend on this, and build successfully, be them 32 or 64-bit applications.

4. 64-bit builds no longer require any patching of ./configure.

5. fltk 1.3 no longer depends on any external libs, so it has no dependencies.

6. Fixed livecheck to work

Also, setting the mandir for the configure was not needed, fltk's configure sets it properly already.

Thank you for the update on fltk. Your changes -almost- work; I'll check-in an update as soon as I've tested everything.
