Rename alias definitions by both aliased and alias name

[emaste]

Third try to spell 'soname'

[• rafael]

Why do we need both? Why not, for example

def alias_library_path ....

LGTM with a nit.

I'd name this alias_Llibrary_path (two extra for --).

(in case we want to define two aliases, say -foo and --foo)

alias_l__library

That was my original thought, but then I noticed that the existing Bdynamic... ones have both. That approach has the nice property that multiple aliases for the same option are grouped together when sorting them alphabetically.
