classpath: only allow on supported architectures

Browse Source 
In commit a75ab1fc1d ("package/classpath:
Don't depend on jamvm"), we removed the dependency of classpath on
jamvm. Since jamvm is only available for a reduced set of architectures,
classpath could until this commit until be built on those architectures.

However, now that this dependency has been removed, classpath can
potentially be built for all architectures supported by Buildroot, even
though it doesn't support all of them.

Since adding support for additional architectures in classpath doesn't
make much sense, because classpath is in Buildroot only usable with
JamVM anyway, and JamVM is only available for a small set of
architectures, this commit simply makes classpath available on the
architectures that it supports.

By doing so, it also removes the or1k support patch which was added by
commit f12a146f81, since anyway or1k is
not supported by JamVM.
