[Andrew Morton]

has been removed from the -mm tree.  Its filename was
     selftests-exec-make-binaries-position-independent.patch

of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Date: Tue, 16 Apr 2024 20:28:29 +0500

The -static overrides the -pie and binaries aren't position independent
anymore.  Use -static-pie instead which would produce a static and
position independent binary.  This has been caught by clang's warnings:

  clang: warning: argument unused during compilation: '-pie'
  [-Wunused-command-line-argument]

Tested with both gcc and clang after this change.
