pipe named FIFO special file is being created in execveat.c to perform some tests. Makefile doesn't need to do anything with the pipe. When it isn't found, Makefile generates the following build error:

Ah, good catch. However, I think this should be moved to EXTRA_CLEAN instead of only removed from TEST_GEN_FILES. (i.e. "pipe" is created by tools/testing/selftests/exec/execveat.c and should be removed.
Hi,
Thank you. tools/testing/selftests/exec/execveat.c creates pipe file and removes it after performing the test on it. I've looked at the code path between creation and deletion of this file. It'll always be removed automatically. So we shouldn't add it to EXTRA_CLEAN.
Thank you for finding and fixing the problem.
I see that pipe is created in prerequisites() and removed from run_tests() after executing non-regular file test. The change looks fine and I ran a quick test and it looks good.
On a separate note the test use its own Makefile for running a test and copies it over in TEST_FILES - Just a bit strange, all seems to work well.

I can pull this in for rc3.
