This is the part that doesn't work and why I talked about having expression
evaluation in the linker scripts: You cannot use a separate memory area for
the heap, because this memory area must start where the program ends - and it
is currently not possible to use an expression for the start address of a
memory area.

This is possible and already used for some targets. But I still think it
should be difficult to use target specific modules, so people try to avoid it.
Many people have a tendency to use machine specific code even where it is
completely unnecessary, so someone has to work against this trend:-)
