Do you mean distcheck, particularly VPATH builds?  If it also breaks `make
dist', please explain.

I see.  Unfortunately, for tools that do not have any concept of input file
search paths the only portable solution seems to be to add an explicite
$(srcdir)/ to every input file.  This results in minor visual clutter in
non-VPATH builds (each file is addressed as ./file instead of just file) and
medium clutter in the Makefiles.
