BIRD 2.0.2 documentation build failure

Hello,

I'm trying to build the documentation of BIRD 2.0.2 on Fedora and RHEL/
CentOS 7 which fails like this:

--- snipp ---
+ /usr/bin/make -j4 -C doc
make: Entering directory `/builddir/build/BUILD/bird-2.0.2/doc'
make: Leaving directory `/builddir/build/BUILD/bird-2.0.2/doc'
make: *** No rule to make target `/tools/progdoc', needed by `prog.sgml'. Stop.
--- snapp ---

When I decided to replace "$(srcdir)" in doc/Makefile by ".." it goes
further, but still fails. Replacing "$(objdir)" by "../obj" and finally
replacing "$(doc-srcdir)" by "." leads to the message that bird.sgml has
a loop reference (which leads to an empty bird.sgml). And when removing
this target,

$(o)%.sgml: $(s)%.sgml $(objdir)/.dir-stamp
    cp $< $@

the documentation build even succeeds. In total that's then this diff:

Do you have any pointers? Is this a bug in BIRD or is this a Fedora/RHEL
build system issue?
