vm test build fails when test is built by itself using

make -C tools/testing/selftests/vm or cd tools/testing/selftests/vm; make

When the test is built invoking its Makefile directly, it defines OUTPUT which conflicts with lib.mk's logic to install headers.

make --no-builtin-rules INSTALL_HDR_PATH=$OUTPUT/usr \ ARCH=x86 -C ../../../.. headers_install make[1]: Entering directory '/mnt/data/lkml/linux_5.2' REMOVE shmparam.h rm: cannot remove '/usr/include/asm-generic/shmparam.h': Permission denied scripts/Makefile.headersinst:96: recipe for target '/usr/include/asm-generic/.install' failed make[3]: *** [/usr/include/asm-generic/.install] Error 1 scripts/Makefile.headersinst:32: recipe for target 'asm-generic' failed make[2]: *** [asm-generic] Error 2 Makefile:1199: recipe for target 'headers_install' failed make[1]: *** [headers_install] Error 2 make[1]: Leaving directory '/mnt/data/lkml/linux_5.2' ../lib.mk:52: recipe for target 'khdr' failed make: *** [khdr] Error 2
