As the name 'local' says (to me, at least), what is in /usr/local
should be treated as local. Hence a global compiler should not at
all have knowledge of, or be interest in, what is in /usr/local.

I do hope that use of configure etc is rare with Ada. Reason 1:
Ada itself has good configuration facilities. Reason 2: Make is pretty
good in steering them. Ada compilation systems tend to have project
compilation management programs. Reason 4: Unlike Ada, auto* is horribly
non-portable across OS toolsets, and has been shown to contribute to the
problem it is supposed to solve.
