[PATCH v2 06/11] x86/efi: discard .text.header for PE binary

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

The multiboot headers are not consumed in the PE binary, hence discard them
in the linker script when doing a PE build.

That removes some relocations that otherwise appear due to the usage of the
start and __efi64_mb2_start symbols in the multiboot2 header.

No functional change intended.

We could also place the multiboot header in it's own isolated section and
skip such section for relocations generation in mkreloc, but it seems best
to just remove the code if it's unused.
