When simply running `make' from the selftests top dir, this error shows up:
cc -O2 -g -std=gnu99 -Wall -I../../../../usr/include/ -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/uuid gpio-mockup-chardev.c ../../../gpio/gpio-utils.o -lmount -o gpio-mockup-chardev cc: error: ../../../gpio/gpio-utils.o: No such file or directory <builtin>: recipe for target 'gpio-mockup-chardev' failed make[1]: *** [gpio-mockup-chardev] Error 1
because the output directory is set to "selftests/gpio" and all binaries built from ../../../gpio/ end up there. In fact, they appear as, exempli gratia: * gpiogpio-event-mon * gpiogpio-hammer * gpioinclude/ * gpiolsgpio which is wrong, as it's missing a directory separator somewhere.
This patch sets straight the output directory when building ../../../gpio/ so that binaries don't cross paths.
