Do not do this. Alpha has an architectural limit of 8k got entries
per object file. To-date, no single source file has crossed this
limit, so it hasn't been a problem.
When the objects are left separate until link time, the linker can
arrange for each of them to have their entire 8k quota.
When you start smashing object files together, the resultant object
file still has the 8k per-object limit. Put enough of them together
and it's relatively easy to make the link fail.
