[PATCH 1/2] bitbake: tweak help text for -C slightly

[Paul Eggleton]

What is specified is a command (or "cmd" as in the help text for -f)
rather than a task - i.e. you specify compile, not do_compile, so change
the sentence to reflect that and reorder it slightly so it makes sense.

[PATCH 2/2] lib/bb/siggen.py: log when tainting the signature of a task

[Paul Eggleton]

Log a note when applying a taint to a task signature (e.g. when using
the -f or -C command line options) so that the user knows this has been
done.
