This produces a PIE binary with a variety of p_align requirements,
suitable for verifying that the load address meets that alignment
requirement.

Add a named pipe as an exec target to make sure that non-regular
files are rejected by execve() with EACCES. This can help verify
commit 73601ea5b7 ("fs/open.c: allow opening only regular files

Test that trivially recursing script onto itself doesn't work.
Note: this is different test from ELOOP tests in execveat.c Those test
that execveat(2) doesn't follow symlinks when told to do so.
