taglib fails to build with gcc-4.2, needs cxx_standard 2011

[barracuda156]

Universal build on Leopard fails almost immediately with:

g++-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags
make[2]: *** [taglib/CMakeFiles/tag.dir/mpeg/mpegfile.cpp.o] Error 1
make[2]: *** Waiting for unfinished jobs....

Single-arch build fails later, with numerous errors:

Looks like it uses cppunit without tests variant being chosen.

Adding compiler.cxx_standard 2011 for a general case fixes the build. Then, to fix universal we also need muniversal 1.0, or if it breaks Clang builds, then:

platform darwin powerpc {
    PortGroup muniversal 1.0

}

After these two fixes made, it builds fine:

36-43:~ svacchanda$ port -v installed taglib
The following ports are currently installed:
  taglib @1.13_0+universal (active) requested_variants='+universal' platform='darwin 9' archs='ppc ppc64' date='2022-11-12T11:24:44+0800'
