[PATCH] build: fix make distclean

[Juergen Gross]

"make distclean" will complain that "-c" is no supported flag for make.

Fix that by using "-C".

The error has been present for a long time, but it was uncovered only
recently.

And that's because the rule simply was unreachable before? Or it was
reachable, but only via special (non-default) $(MAKE) invocations?

To distinguish from this commit's title and to also identify the affected
component, how about having "gdbsx" somewhere in the subject? (To be
honest, with this title I wouldn't even have expected the issue is in the
tool stack part of the tree.)

Preferably with the above taken care of (which could be done while
committing, provided suitable adjustment suggestions),

I just hit the bug during a top level "make distclean" and looked which
commit introduced it. As it was really old, I looked for a more recent
commit which could trigger the bug and found the rather recent one,
making me believe that the wrong rule was never reached (other than by
a "make" in the local directory of that rule).

I didn't spend more time on digging out whether the problem could have
happened in other cases, too.

Hmm, yes, the prefix could be changed to "tools/debugger".
