Subject: [PATCH 4.14 65/69] selftests: futex: Use variable MAKE instead of make

From: Muhammad Usama Anjum <usama.anjum@...labora.com>

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.

Fixes: a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT")
