<pre>If a build-id is included in an input object file, lld may adds a new one, and
as a result, the output contains more than one .build-id. Most tools don't
expect such executables and don't work well.
This is a test case to create an executable with two .build-id's.
We probably should strip .build-id sections from input files if --build-id is
specified.
