Enable LTO build (#77)
* fix(Makefile): Don't double up on optimisation flags

This is already provided by BUILD_CFLAGS later on

* feat(common): Mark explicitly-placed things as used

If we put something in a given section, we should be able to expect it to actually turn up in that section!

Doing this will prevent LTO from slurping all the hooks away as "unused".

* feat: Enable LTO

This uses "fat" binaries, so normal builds won't break, but also includes the LTO data for builds that wish to use it
