Likely, since some patches depend on each other I was unable to revert
a single commit.

Anyway as far as I am concerned there are two separate
build targets, the bare u-boot having an (almost) naked compiler, beside
stdarg and stdbool? without any other host includes or objects (well with
CONFIG_USE_PRIVATE_LIBGCC=y). U-boot provides linker scripts for them,
and we have fine grained control over them and an excuse to throw any
trick at them if it makes things faster / smaller etc. It is still nice 
if this
compiles anywhere though..

On the other hand there are "tools" for the host / target userland, which
should build against the host / targets "std*". Those things should be 
buildable
on any decent host / target and be straightforward (and _not_ define KERNEL
etc, since it are userland tools). There is no linker for them afaik, so 
tweaking
them seems like a bad idea. Hence I am tempted to remove the use of
linker generated lists from tools...

Sandbox used to build on FreeBSD, but it is quite a mess at the moment.
But a I said, I think the best solution for tools is not to use linker 
generated
list in the first place for tools.
