Subject: kbuild: fix make -jN with multiple targets with O=...
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=296e0855b0f9a4ec9be17106ac541745a55b2ce1;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

kbuild: fix make -jN with multiple targets with O=...

The way multiple targets was handled with make O=...
broke because for each high-level target make spawned
a parallel make resulting in a broken build.
