Is LTO_REFERENCE_INITCALL() still needed?

[Luis R. Rodriguez]

Andi,

is LTO_REFERENCE_INITCAL() still needed?

I see external stuff like this:

https://github.com/neo-technologies/linux-next/blob/master/scripts/Makefile.lto

But nothing quite obviously setting these upstream. I'm probably just
missing something obvious though. Either way I figured now would be a
good time to ask as I have other code that would use this, the linker
table stuff I've been working. If we can avoid propagating more use of
LTO_REFERENCE_INITCALL() then great. If we still need it its probably
good to document this a bit more as can't see anything super clear.
