--- Comment #7 from Mark Wielaard <mark at klomp dot org> ---
Turns out supporting (gabi) compressed ELF sections in eu-elflint is is fairly
simple by just decompressing every section unconditionally at the start (when
we also check if all sections are actually there):
diff --git a/src/elflint.c b/src/elflint.c
index e0c65b6..51e53c2 100644
--- a/src/elflint.c
+++ b/src/elflint.c

scn = elf_nextscn (ebl->elf, scn);
if (scn == NULL)
break;
+ /* If the section wasn't compressed this does nothing, but
+ returns an error. We don't care. */
+ elf_compress (scn, 0, 0);
}
if (scnt < shnum)
ERROR (gettext ("Can only check %u headers, shnum was %u\n"), scnt,
shnum);

Would you be able to test that on your s390x setup?
