Currently, many tests hardcode to older versions of gcc for comparisons of
concretization among compiler versions. Those versions are too old to concretize for
`aarch64`-family targets, which leads to failing tests on `aarch64`.
This PR fixes those tests by updating the compiler versions used for testing.
Currently, many tests hardcode the expected architecture result in concretization to the
`x86_64` family of architectures.
This PR generalizes the tests that can be generalized, to cover multiple architecture
families. For those that test specific relationships among `x86_64`-family targets, it
ensures that concretization uses the `x86_64`-family targets in those cases.
Currently, many tests rely on the fact that `AutotoolsPackage` imposes no dependencies
on the inheriting package. That is not true on `aarch64`-family architectures.
This PR ensures that the fact `AutotoolsPackage` on `aarch64` pulls in a dependency on
`gnuconfig` is ignored when testing for the appropriate relationships among dependencies
Additionally, 5 tests currently prompt the user for input when `gpg` is available in the
user's path. This PR fixes that issue. And 7 tests fail currently when the user has a
yubikey available. This PR fixes the incorrect gpg argument causing those issues.
