Drop ramstage.a
ramstage.a has two issues:
1. duplicate source filenames don't survive the ar(1)
treatment properly (so files aren't considered)
2. ld doesn't resolve symbols if it isn't forced to, in
particular no overrides of weak symbols
Downside: The resulting binaries get slightly larger.
Link time optimizations should fix that, as would tighter
rules in the build system (to not compile unused code in
the first place).
