[PATCH] selftests/exec: Fix building of exec test

From: Michael Ellerman
Date: Wed Nov 04 2020 - 05:07:15 EST


Currently the exec test does not build:

make[1]: Entering directory '/linux/tools/testing/selftests/exec'
...
make[1]: *** No rule to make target '/output/kselftest/exec/pipe', needed by 'all'.

This is because pipe is listed in TEST_GEN_FILES, but pipe is not
generated by the Makefile, it's created at runtime. So drop pipe from
TEST_GEN_FILES.

With that fixed, then install fails:

make[1]: Entering directory '/linux/tools/testing/selftests/exec'
rsync -a binfmt_script non-regular /output/install/exec/
rsync: link_stat "/linux/tools/testing/selftests/exec/non-regular" failed: No such file or directory (2)

That's because non-regular hasn't been built, because it's in
TEST_PROGS, it should be part of TEST_GEN_PROGS to indicate that it
needs to be built.
