It requires you to perform a partial build, install the results, drop
binaries into the installation tree, and repeat; and it does not
accomplish the goal, which is to test construction of the complete
tree, _including_ Ada, with the vendor-provided tools.

You are assuming that the GCC driver with Ada support can handle C,
which is not necessarily the case.  As it happens, the one on my
system does include a cc1 - but it's 2.8.1-based, and therefore does
not work with glibc 2.2.x, so it might as well not exist.

Turn it around: The changes I made to ada/Makefile.in are
straightforward and obvious, and they make the build work out-of-box
for a large category of users that would otherwise have to go to
considerable extra trouble.  Why do you object so strenuously?
