Currently the gpio selftests fail to build if the source tree is read
only:

  make -j 160 -C tools/testing/selftests TARGETS=gpio
  make[1]: Entering directory '/linux/tools/testing/selftests/gpio'

  ln: failed to create symbolic link '/linux/tools/gpio/include/linux/gpio.h': Read-only file system

This happens because we ask make to build ../../../gpio (tools/gpio)
without pointing OUTPUT away from the source directory.

To fix it we create a subdirectory of the existing OUTPUT directory,
called tools-gpio, and tell tools/gpio to build in there.
