If an external environment storage should be used in very rare and special cases,
the intentional behaviour should be to ignore the external environment and always
fall back to the built-in environment. By storing an empty "to be ignored" environment
into the external environment a confusing error message about invalid CRC sums will go
away and still the built-in environment is used.
With this new option we can force the intentional behaviour.

In order to be able to mark an stored envfs image with special features
(intentional ignore for example), we now can feed forward these flags.
By forwarding a '0' for the flags nothing changes because the envfs superblock
was already allocated with xzalloc.

so remove its inclusion.

This implements two new options for the loadenv command:
-s: removes (scrubs) old directory contents to be able to
create a fresh environment from for example /dev/defaultenv
-n: no overwrite. Do not overwrite existing files. This allows
to keep parts of the old environment.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

When barebox headers get included from HOSTCC tools they should not
include other architecture specific headers as barebox might get
cross-compiled. Instead, the tool itself should include "compiler.h".
