Subject: make: clean after distclean deletes source files
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6fd87e74a1c56cbe63691fc33de0b616e6efcff3;p=qemu.git

make: clean after distclean deletes source files

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.
