Simplify ada-exp.o rule

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.
