In 0day builds, $PWD is the obj dir and so we used "-C" too:
wfg@inn ~/linux/obj-compiletest% ls -l source lrwxrwxrwx 1 wfg wfg 2 Aug 24 10:40 source -> ..
wfg@inn ~/linux/obj-compiletest% make M=tools/testing/nvdimm/ ==> /usr/bin/make -C source O=/home/wfg/linux/obj-compiletest ARCH=x86_64 -j32 M=tools/testing/nvdimm/ make: Entering directory '/c/wfg/linux' make[1]: Entering directory '/c/wfg/linux/obj-compiletest' make[2]: *** No rule to make target 'tools/testing/nvdimm//config_check.o', needed by 'tools/testing/nvdimm//libnvdimm.o'.
