musepack: add x86{,_64} to libcuefile, libreplaygain and musepack_tools.

* Add x86 and x86_64 to ARCHITECTURES as the recipe also works fine for these.
* Add x86_gcc2 to SECONDARY_ARCHITECTURES for use in x86 (gcc4) hybrid.
* Use $portVersion instead of the current version in SOURCE_{URI,DIR}.
* Drop the "r" prefix in version (r475 → 475) and ajust SOURCE_{URI,DIR}.
