[PATCH v2 00/15] Various toolchain compatibility fixes/improvements

[Sam Edwards]

Hello again U-Boot list,

This is v2 of my "misc. fixes" series, sent to prepare the codebase for more
direct LLVM support in the near future. This series contains several fixes that
I found in the process of preparing that support and which address issues
independent of any future feature or enhancement. I am sending these now, both
so that their inclusion is not delayed by discussion on my upcoming series and
to make the latter more manageable.

PLEASE APPLY PARTIALLY! I have tried to sort these so that the most
straightforward changes come first. If any patch proves contentious, you can
either skip it or stop applying the series at that point. Any patches that need
revisions will be included in a future series, but I'm trying to avoid there
being a v3 of *this* series. :)

Happy Saturday,
Sam

Changes v1->v2:
- Carried forward acked/reviewed tags
- Dropped two patches (one was incorrect, the other can be fixed differently)
- Minor phrasing changes to commit messages
- Instead of removing `ENTRY(_start)`, I instead added `.globl _start` where
  appropriate, in the EFI apps
