Subject: [PATCH 1/4] UEFI 2.10 fixes

Revert "Align sections to 512 bytes"

This is not permitted according to the Microsoft
guidelines which require section alignment to be
the same as the page size of the architecture which
for all supported archs is the default in Binutils

https://techcommunity.microsoft.com/t5/hardware-dev-center/new-uefi-ca-memory-mitigation-requirements-for-signing/ba-p/3608714

This reverts commit c60c0b8dfda71275ab40bdb316a6ca650c7a8948.

Keep .areloc ARM32 section

This is the psuedo .reloc section but renamed only on ARM32 to avoid
a bad RELSZ value (gnu-efi 3.0.18+)

Only use 4KiB pages on aarch64

Binutils is currently configured by default
to use 64KiB pages on aarch64, however this
is not allowed by the UEFI specification

Check if crt0 contains .note.GNU-stack section

We need the .note.GNU-stack section for NX
compat. If we don't have a new enough
gnu-efi, error as the gnu-efi libraries
themselves must have been built as NX
for this to work

Subject: [PATCH 2/4] crt0/lds: Update from upstream gnu-efi

- Set NX in aarch32/aarch64 crt0
- Update crt0 from gnu-efi
  * Can now be read successfully by
    Microsoft dumpbin
  * Avoid GNU as portability errors
  * Ensure .rel(a).plt section is included
    causes gap in section table on x86_64/ia32
