[PATCH 00/27] x86: efi: Various app improvements to support bootstd

This series makes a number of improvements to the EFI app. Mostly it
applies to x86 but the ARM version will share some improvements.

The main updates are:
- Improve linker scripts and options to detect missing symbols and
  remove unused code

  script
