Fix multiArch installs where only some archs are available.

In this case, NO_MATCHING_ABIS shouldn't result in a failure
when we're trying to match against one of SUPPORTED_32_BIT_ABIS
or SUPPORTED_64_BIT_ABIS.

There shouldn't be a general requirement that packages must
contain both 32 and 64 bit libs because it might legitimately
exclude one or the other for reasons such as compatibility
etc.
