Why doesn't ADA testsuite use newly built gnatchop/gnatmake?

Ada testsuite log gives very little information. I got many

Running chapter a ...

on Linux/x86. To reproduce,

1. Build gcc 3.4 with ada.
2. Install gcc 3.4.
3. Replace gnat1 in the installed gcc 3.4 directory with a dummy shell
script which returns 1.
4. Run "make check-ada" and watch massive failures.

It looks like Ada testsuite forgets to make sure the newly build Ada
compiler is used instead of the installed one.
