Add initial experimental LTO support
This will not succeed in compiling on all target and compiler
combinations but at least gets the ball rolling. The change is not
invasive.
Some notes:
- GCC has issues with LTO on ARM
- Clang uses LLD automatically on some arch
- Clang with LTO fails on x86 as it forwards the linking to GCC for some
reason
- SMM building succeeds but the binary is empty
