configured with --prefix=/home/mjw/src/gcc/install --enable-languages=c,ada
using Debian's Gnat 3.13p-8 as the host Ada compiler
>Description:
After bootstrapping, I got the following error during 'make
gnatlib_and_tools':

ln /home/mjw/src/gcc/gcc-cvs/gcc/ada/5lml-tgt.adb tools/mlib-tgt.adb
ln: creating hard link `tools/mlib-tgt.adb' to `/home/mjw/src/gcc/gcc-cvs/gcc/ada/5lml-tgt.adb': Invalid cross-device link

After this, the build failed to continue. I have srcdir and
objdir on different filesystems.

Replacing '$(LN)' with 'cp' in the following fragment of
gcc/ada/Makefile was sufficient to let the build complete:

stamp-tool_src_dir:
	-$(RMDIR) tools
	-$(MKDIR) tools
	-$(LN) $(fsrcdir)/$(MLIB_TGT).adb tools/mlib-tgt.adb
	touch stamp-tool_src_dir
