[PATCH] make: clean after distclean deletes source files

[PATCH] make: clean after distclean deletes source files

[Steve Sistare]

Run 'make distclean' in a tree, and GNUmakefile is removed.
But, GNUmakefile is where we change directory to build.
Run 'make distclean' or 'make clean' again, and Makefile applies
the clean actions, such as this one, at the top level of the tree.
For example, it removes the .d source files in 'meson/test cases/d/*/*.d'.

    find . \( -name '*.so' -o -name '*.dll' -o \
          -name '*.[oda]' -o -name '*.gcno' \) -type f \
        ! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-aarch64.a \
        ! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-arm.a \
        -exec rm {} +

To fix, remove clean and distclean from UNCHECKED_GOALS, so those targets
are "checked", meaning that configure must be run before make.  However,
the check action does not trigger, because clean does not depend on
config-host.mak, so change the action to simply throw an error.

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

[Steven Sistare]

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 ...
