[Xen-devel] [PATCH 1 of 2] xen: add "lto=y" option to build Xen with link-time optimizations

[Tim Deegan <Tim.Deegan@xxxxxxxxxx>]

This involves gathering object files from .asm (which will be binary)
and object files from .c (which will be in LTO format) separately
until the final link.

Only tested for x86_64 Xen builds using Clang/LLVM bitcode; it should be
possible to do the same with newer GCCs and GIMPLE.
