[Ada] Remove couple of left-overs in build machinery

[Eric Botcazou]

This removes a couple of left-overs from the pre toplevel bootstrap era.
No functional changes.  This paves the way for a real change that we want to 
enable for the 4.8.0 release.

Tested on x86_64-suse-linux (w and w/o --disable-bootstrap), applied on the 
mainline.

        * gcc-interface/config-lang.in (boot_language_boot_flags): Delete.
        * gcc-interface/Make-lang.in (BOOT_ADAFLAGS): Likewise.
