3.2 PATCH: Fully support parallel gnat1/gnatbind builds

[Richard Kenner]

    $ gcc test.adb
    gcc: test.adb: Ada compiler not installed on this system
    $ gnatgcc test.adb 
    test.adb:1:01: compilation unit expected

    and this is unlikely to change for at least a year.  We've been
    through this /ad nauseam/ already.

Perhaps, but what makes you think that using "gcc" to compile the C
code and "gnatgcc" to compile the Ada code will produce an object file
that will work?  You need to use the *same* compiler for everything.
