Subject: [PATCH] procps: fix build with new glibc but old kernel headers
If you're building procps with a newer glibc (with pidfd_open()) but
older kernel headers (say 4.x, before __NR_pidfd_open) then procps will
fail to build because of a typo in configure.ac.

+Subject: [PATCH] Fix pidfd_open detection
+
+This check for pidfd_open uses AC_CHECK_FUNC which just runs the specified code, but
+src/pgrep.c checks HAVE_PIDFD_OPEN which will only be defined by AC_CHECK_FUNCS.
+
+Also pidfd_open is defined in sys/pidfd.h so that needs including.
