The cc1/cc1plus/f951/... binaries are normally linked with
-static-libstdc++ -static-libgcc in second and later stages (first
stage is linked against the host libstdc++, so not a problem, but
even that stage is often linked with it).
See e.g. --with-static-standard-libraries configure option in toplevel
configury.
Perhaps you don't link cobol1 with the correct make variables
as other FEs are linked?
I think it is $(LDFLAGS) that is needed:
grep ^LDFLAGS *gcc/Makefile
gcc/Makefile:LDFLAGS = -static-libstdc++ -static-libgcc
prev-gcc/Makefile:LDFLAGS = -static-libstdc++ -static-libgcc
stage1-gcc/Makefile:LDFLAGS = -static-libstdc++ -static-libgcc
but better follow what other FEs do in Make-lang.in
E.g. the linking of the FE binaries need to be specially chained for
--enable-link-serialization
or
--enable-link-serialization=N
such that only N binaries are linked together, etc.
c++.serial = cc1plus$(exeext)

does that (the lang.serial line, $(lang.prev) dependency, the
LINK_PROGRESS.lang calls, using $(LLINKER) $(ALL_LINKERFLAGS) $(LDFLAGS) ...
$(BACKEND) $(BACKENDLIBS) $(LIBS) too.
