[PATCH pushed] gdbserver: Clear .deps on clean

[Simon Marchi <simon.marchi@ericsson.com>]

I have just pushed this:

In some situations, the dependency tracking files in .deps can refer to
source files that were removed or renamed, leading to errors like:

  make: *** No rule to make target `version.c', needed by `version.o'. Stop.

This patch makes the clean target clear the .deps directory, which gives
the user a chance to recover from the error wihtout knowing about the
internals of the build system.

It is already done for GDB.  See here for more details:
