auto-solib-add for "attach" as well as "run"

[Michael Elizabeth Chastain]

I have an enhancement request where a gdb user wants the
"auto-solib-add" flag to work with the "attach" command as well
as the "run" command.

Superficially, this looks like an entirely reasonable thing to do.
"run" and "attach" are different in how they handle processes,
but ought to work the same for the whole symbol-handling side of
the debugger.

Can anyone point out any gotchas or drawbacks if I just go ahead
and make "attach" honor the "auto-solib-add" flag?
