Comment (by gk):

 Actually that is wrong. The second difference is a different CRC32
 checksum in the .gnu_debuglink section which is caused by the same build
 id in the corresponding debug file. So, the questions boil then down to:

 1) How could the different build ID get created in the first place, given
 that the contents of the libxul libs don't differ?
 2) What can we do about that problem?

 ad 1) I don't know, honestly. The default method to generate a build ID is
 SHA1 which should *not* emit different hashes given the same library
 contents.
 ad 2) A workaround is disabling the build ID in the libraries. We don't
 need it if we use the debuglink method (as well) (See:
 https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html). This
 will be done in a different bug, though.
