Message:

Use -ffunction-sections and —gc-sections

This change results in vast reduction of binary image sizes. For example, the
amd64 ISO image was 38MiB before this change and is only 25MiB after the change.

Unfortunately the ia64 linker ignores —gc-sections for some reason so it cannot
be turned on globally.
