I haven't covered "generic" CPAN XS, per se, but truth be told, we're
basically there. If it's a single .xs file involved, you ought to be able
to compile and link if you have PerlStub, MathLib, RunTimeLib and the
appropriate C or C++ lib. Sometimes a library or two will be redundant,
but I've been working towards describing a set that covers 99% of all
cases. ToolBox stuff needs InterfaceLib also.

The default *BuildRules files, as they exist right now, don't necessarily
handle multiple source files quite right, so you have to fiddle with them.
Math::Random is one of these. So until I cover this situation, one
approach is to BuildProgram, let it fail, and extract the offending
command from the *.makeout' file, edit it, and rerun it by itself.

But that's what I'm really working towards: "generic" builds. If it's a
question of porting, well, that's C or C++ knowledge - another matter
entirely.
