Error trying to bootstrap gnat openbsd cross-compiler

[Marc Espie]

gcc 3.1 release, + config/i386/openbsd.h patch needed to
bootstrap C compiler (committed today), and removing the
contents of config/i386/t-openbsd, since mainstream binutils
does not support pic code on OpenBSD.

binutils bootstrapped with --target=i386-unknown-openbsd
without problems.

gcc 3.1 configured with only C and ada sources present, with 
a gnat-3.14p-i686-pc-linux-gnu-bin.tar.gz working gnat compiler,
using 
configure --target=i386-unknown-openbsd

make worked.
I tried to build the tools and library using
make gnatlib_and_tools
and I got to:

../../xgcc -B../../ -c -g -O2 -g -O2   -W -Wall -gnatpg -I.  -I/home/espie/ada/gcc-3.1/gcc/ada s-auxdec.adb

No source file to include, no nothing...

Any idea ?
