Can you clarify what is your setup?

Are you using a remote host test setup?  This would mean that you
cross-compile and "make check" on your host (e.g. your x86-64 machine),
but the testsuite uploads the gdb binary in the VM and runs it there.
And GDB itself would debug the local system natively (in the VM).

Or, are you using a remote target test setup, where the testsuite starts
a gdbserver in the VM and GDB runs on the (e.g. x86-64) host?

Either way, it sounds like that test you mention would be broken either
way, as SHLIB_NAME would be a path on the host.  This would be a
mistake, it would need to be fixed.  Not many people are using remote
host/target test setups, so these mistakes tend to creep in a lot.
