[3/4] Simplify ada-exp.o rule
Commit Message
The ada-exp.o rule no longer needs to pass -Wno-old-style-definition
to the compiler, as this option has no meaning in C++. So, This patch
simplifies the explicit ada-exp.o rule in the Makefile. The rule is
still needed because, according to the comment, ada-exp.c may appear
in the srcdir.

For the record, this is correct; in particular, the source packages
we produce (nightly and releases) include them. I believe this helps
avoid a dependency on bison (and flex for ada-lex.[lc]) for users
building from source packages rather than from git sources.
