Subject[PATCH v2 01/10] selftests/x86: Extend Makefile to allow 64-bit-only tests
Date
Previously the Makefile supported 32-bit-only tests and tests that
were 32-bit and 64-bit. This adds the support for tests that are
only built as 64-bit binaries.

There aren't any yet, but there might be a few some day.
