e2fsprogs needs to build with partial relro support

Description of problem:
Description of problem:
The e2fsprogs package contains libraries (specifically libcomm_err). We would like them to be built with partial RELRO support as a security enhancement.
Partial RELRO requires these passed at link: -Wl,-z,relro
You can fix this by patching the Makefiles to add this link flag to LDFLAGS or you might be able to simply add LDFLAGS="$LDFLAGS -Wl,-z,relro" to the configure line in the rpm's spec file. You will have to test the built packages to ensure the flags are properly passed all the way to the end of build. It does not hurt anything if the package contains applications that pick up partial relro support, too.
I don't understand why this is reported as an issue 4 days before it is due to be resolved?
We have a planning phase that closed a long time ago. That is when you need to make this kind of request please!
Aside from the poor timing, can I get a little background?
What are the implications of this? Should the entire package build with
those flags? What does this fix, and why is libcom_err so special in this
