How does it slow down the sorting?
It seems a little strange at least to drop the *ABS* section, since IIUC
that's for symbols that specify some kind of absolute address. Couldn't
these matter for lookup purposes? It's probable I don't really know
what's going on here...
I wonder if we can drop all support for all these sections from gdb.
