The use of $$OUTPUT in the target shell commands resulted in an empty
string followed by an absolute path for which mkdir failed:
$ make -C tools/testing/selftests/futex
make: Entering directory '/home/dvhart/source/linux/linux-pdx86/tools/testing/selftests/futex'
Makefile:36: warning: overriding recipe for target 'clean'
../lib.mk:55: warning: ignoring old recipe for target 'clean'
for DIR in functional; do \
BUILD_TARGET=$OUTPUT/$DIR; \
mkdir $BUILD_TARGET -p; \
make OUTPUT=$BUILD_TARGET -C $DIR all;\
done
mkdir: cannot create directory ‘/functional’: Permission denied
Replace $$OUTPUT with $(OUTPUT) when referring to the Makefile OUTPUT
variable. The above make command now completes successfully.
