[Bug ada/43749] New: installed gnat cannot find installed libraries when exec-prefix != prefix

[dougsemler at gmail dot com]

When building a compiler with --prefix=/some/dir and
--exec-prefix=/some/dir/subdir, the installed gnat cannot find the installed
libraries in /some/dir/subdir/lib/gcc/...

I believe that sdefault.adb should be generated with 

S0 : constant String := \"$(exec_prefix)/\";"
not
S0 : constant String := \"$(prefix)/\";"

in gcc/ada/Make-generated.in - when I modify as above, the installed gnat is
able to find the installed adainclude and adalib correctly.  (And the problem
doesn't occur in the build tree, so the issue isn't apparent until the
installed toolset is used).

Looks like both are duplicates of
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15819. Back then it has been noted
that it's just not supported.

You're right.  When I searched for it, it reported no bugs found (sigh).

And I see my solution is exactly the same as 38493.
