You made this change (54beacab):
2004-09-20 Jakub Jelinek <jakub@redhat.com>
* configure.in (libc_cv_z_relro): Only set to yes if linker script
contains DATA_SEGMENT_RELRO_END.
I want to rewrite the test based on grepping the linker script with a
proper empirical test for the necessary linker behavior. Can you tell me
what was the specific misbehavior of older linkers that grokked -z relro
but didn't use DATA_SEGMENT_RELRO_END that you needed to check for?
Thanks,
Roland
