Prarit Bhargava ff592819e5 randstruct: Split randstruct Makefile and CFLAGS
JIRA: https://issues.redhat.com/browse/RHEL-25415

Conflicts: Minor drift issues in the vdso Makefile.

commit 613f4b3ed7902d1dbbc6ade6401e452a63dfbc21
Author: Kees Cook <keescook@chromium.org>

    randstruct: Split randstruct Makefile and CFLAGS

    To enable the new Clang randstruct implementation[1], move
    randstruct into its own Makefile and split the CFLAGS from
    GCC_PLUGINS_CFLAGS into RANDSTRUCT_CFLAGS.
