I'd better set CROSS_COMPILE in the environment than change my path,
so CROSS_COMPILE is conditionally assigned.

The revision is better "git describe --dirty" than "git rev-parse". The output
is a short beautiful string like "wrpc-v2.0-13-g09a736d5

"
with an optional "-dirty" trailer, to show we compiled a non-committed
change.

Finally, to execute commands we dont $(shell) at toplevel, but have
them in the build rule.

This is massive: 4k lines changed (but only 840 if you ignore
space-only changes).  In this case "git blame -w" won't always find
the right patch, and it may fall on this patch -- because those
800 lines changed in content too.

This has been done with

   find . -name '*.[ch]' | xargs -n 1 ./scripts/Lindent

Statistics: all changes and ignoring blank space:

   morgana% git diff --stat HEAD~1 | tail -1
    77 files changed, 3774 insertions(+), 3709 deletions(-)
   morgana% git diff -w --stat HEAD~1 | tail -1
    61 files changed, 894 insertions(+), 829 deletions(-)

However, after this step I hand-fixed some very ugly long expressions
(leaving them long: no content change at all is there).

If you find this patch with "git blame" please use "git blame -w"
to have all white-space ignored while associating lines to commits.

This commit has no practical effect but cleanup. I made it
with sed like this:

  git grep -l '[ \t]$' | xargs sed -i 's/[ \t]*$//'

However, I had to manually restore doc/wrpc_mon.png after the fact.
Similarly, I restored the include/hw/*regs.h files, as they
are (most likely) auto-generated.
