stable inclusion from stable-v5.10.99 commit 1536fafa23ac072ab1a8293ed8efca808b20cfa7 bugzilla: https://gitee.com/openeuler/kernel/issues/I55O7H
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit b9199181a9ef8252e47e207be8c23e1f50662620 upstream.
Recursive make commands should always use the variable MAKE, not the explicit command name ‘make’. This has benefits and removes the following warning when multiple jobs are used for the build:
make[2]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule.
