Subject: kbuild: use pattern rule for building built-in.a in sub-directories
X-Git-Tag: v5.6-rc1~90^2~30
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a7499267976ce014fbc6f7defe9080367f94d6cc;p=thirdparty%2Fkernel%2Flinux.git

kbuild: use pattern rule for building built-in.a in sub-directories

The built-in.a in a sub-directory is created by descending into that
directory. It does not depend on the other sub-directories. Loosen
the dependency.
