That works. Didn't know apt already supported the :arch.

The odd behaviour makes sense now. But shouldn't it show the entries for
all architectures if no specific architecture is requested? Just like it
shows all versions if no version is specified.
Short of that it could say what it actualy searched for:
E: Can't select versions from package 'libc6-armel-cross:amd64' as it purely
virtual
E: No packages found
E: Unable to locate package libfoo-armel-cross:amd64
E: No packages found
But showing the right thing would be better.
