Yes, that's right. The files in the Cross directory are used for
all operatins systems (Windows, RiscOS, Mac, various unices), so
in some cases we have library sources in Cross for the benefit of
operating system that may not provide them otherwise.

I cannot check right now, but I suspect that if we delete the offending
files or directories from the source tarball (not from the actual
platforms/Cross in Subversion), then fix up the cmake procedures,
then we might be able to provide a solution to this issue for the
Linux distro maintainers.

> In general it should work fine to delete the embedded library sources and adapting the make files. I'm not familiar enough with cmake to say how exactly, though. However, adding the acinclude.m4 will not work since that is autoconf, not cmake. HowToBuildFromSource hasn't been updated for cmake, yet, unfortunately. 

Although the HowToBuildFromSource is in need of an update, there is
documentation for the CMake build process in the file unix/README.CMake.
The new configure script (replacing the original unix/config/configure),
is unix/cmake/configure. This is just a shell script that sets up some
initial parameters, then calls cmake to set up the build. Running
"unix/cmake/configure --help" is enough to get started. An important
note for Linux distros is to build the VM as a 32 bit executable
(i.e. pass "--CFLAGS='-m32 -O2' " as a parameter to unix/config/configure)
because some parts of the VM are still 32-bit only. 

In general, the unix source tree contains files named config.cmake and
build.cmake that take the place of the acinclude.m4 and Makefile.inc
files that were previously used. Many build issues can be addressed by
modifying the config.cmake or build.cmake for the portion of the source
tree that has a problem.

It would probably be good at this point to clean out the old autoconf
files and update the documentation, although I should note that there
is an important branch of the VM (the high performance Cog VM) that
has a build process based on the old autoconf procedures, so there
may be value in keeping the old files around for reference.
