Cover letter [PATCH 5.15 5.10 0/1] Fix kselftest builds when specifying an output dir

From: "Tyler Hicks" <[email protected]>

When attempting to build kselftests with a separate output directory, a number of the tests fail to build.

For example,

 $ rm -rf build && \
   make INSTALL_HDR_PATH=build/usr headers_install > /dev/null && \
   make O=build FORCE_TARGETS=1 TARGETS=breakpoints -C tools/testing/selftests > /dev/null
 /usr/bin/ld: cannot open output file
 build/kselftest/breakpoints/step_after_suspend_test: No such file or directory
 collect2: error: ld returned 1 exit status
 make[1]: *** [../lib.mk:146: build/kselftest/breakpoints/step_after_suspend_test] Error 1
 make: *** [Makefile:163: all] Error 2

This has already been addressed upstream with v5.18 commit 5ad51ab618de ("selftests: set the BUILD variable to absolute path"). It is a clean cherry pick to the linux-5.15.y and linux-5.10.y branches.
