kbuild: cancel sub_make_done for the install target to fix DKMS
[ Upstream commit 14ccc638b02f9ec500c17d9e39efe979145a4b61 ]
Since commit bcf637f54f6d ("kbuild: parse C= and M= before changing the
working directory"), external module builds invoked by DKMS fail because
M= option is not parsed.
I wanted to add 'unset sub_make_done' in install.sh but similar scripts,
arch/*/boot/install.sh, are duplicated, so I set sub_make_done empty in
the top Makefile.
Fixes: bcf637f54f6d ("kbuild: parse C= and M= before changing the working directory")
