[scarthgap][PATCH 3/8] selftest-hardlink: Add additional test cases

[Mark Hatle <mark.hatle@kernel.crashing.org>]

From: Mark Hatle <mark.hatle@amd.com>

Additional test cases for debug symlink generation both binaries
and static libraries.

This also has the side effect of testing for race conditions in the
hardlink debug generation and stripping.
