Rollup merge of #27019 - akiss77:pr-aarch64-morestack-section, r=alexcrichton

 When building for AArch64/Linux, __morestack ends up in the .note.GNU-stack section,
which causes missing references for the linker. By using the func/endfunc macros
from macros.S we get __morestack right to .text (and a bit more on the side).
