First things first.
So it looks like e2fsprogs is mixing compilers and archs here?
That would be my guess to what's behind the 11.2 / 11.3 error.

But probably more importantly,
enable-lto looks like a misconfiguration to me.
Maybe if it was controlled by a global.
And even then one would probably have to weed out a lot of compile
failures given the rocky history of LTO over a lot of stuff.
I suggest you disable it and submit a patch.

Christian
