The above seems a bit confused.  Are you trying to do a VPATH build?
If so, you need to run configure in the build tree, not the source tree.
That is, I'd have expected something more like

	cd ...buildtree...
	../sourcetree/configure
	cd doc/src/sgml

> make check

You probably want "make" or "make all"; "make check" won't actually
build anything.  However, that's not related to this problem:

> I get the following error:

  Stop.

Looking at the makefile, it's clear that $(top_srcdir) is expanding
to empty.  I'm not quite seeing how Makefile.global would end up
doing that, but perhaps it's confused about vpath vs regular build.
Another theory is that configure went wrong somehow and inserted
bogus values into Makefile.global; was there any sign of distress
while running configure?
