When building the kselftests out-of-tree, e.g.
  | make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \
  |   O=/tmp/kselftest headers
  | make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \
  |  O=/tmp/kselftest HOSTCC=gcc FORMAT= \
  |  SKIP_TARGETS="arm64 ia64 powerpc sparc64 x86 sgx" \
  |  -C tools/testing/selftests gen_tar

the kselftest build would not pick up the correct GENDIR path, and
therefore not including autoconf.h.

Correct that by taking $(O) into consideration when figuring out the
GENDIR path.
