[Bug ada/29802] New: wrong directory in makefile for ada and libada

["Jean-pierre dot vial at wanadoo dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

when building ada on linux (x86-64)
building ada fails because the makefile looks for gnatbuild in
mydir/gcc-4.2-20061107/prev-gcc
instead of
mydir/gcc-4.2-20061107/host-x86_64-unknown-linux-gnu/prev-gcc
I could not find where precisely in the makefile the bug hides.

for libada it is obvious:
the make variable
HOST_SUBDIR
is used, but nowhere defined. 
If I define it, libada is built
