Given my past experience in this area, I'm happy to help out with this,
once I've got my current plans for the debug line work largely concluded,
so from sometime next week probably. My thinking is to simulate the DWARF
usage with blank sections of the appropriate size and with the right number
of relocations, instead of the real contents, to give us a rough idea of
the link-time performance hit of fragmenting using the current LLD.
