Re: [PATCH] make: clean after distclean deletes source files

[Steven Sistare <steven.sistare@oracle.com>]

Any takers?  I believe this patch is correct and clean.
Examples, run in the top level of a git tree:

$ configure ...
$ make clean
... cleans ...

$ make clean
... cleans ...

$ make distclean
... cleans ...

$ make distclean
Makefile:180: *** Please call configure before running make.  Stop.

$ make clean
Makefile:180: *** Please call configure before running make.  Stop.

# unchecked goals still work
$ make cscope
cscope  Remove old cscope files
cscope  Create file list
cscope  Re-index .

$ configure ...
$ make clean
... cleans ...
