rustc: Try again to disable NEON on armv7 linux
|
|
|
|
This is a follow-up to #35814 which apparently didn't disable it hard enough. It
|
|
looks like LLVM's default armv7 target enables NEON so we'd otherwise have to
|
|
pass `-neon`, but we're already enabling armv7 with `+v7` supposedly, so let's
|
|
try just telling LLVM that the armv7 target is arm and then enable features
|
|
selectively.
|
|
|
|
Closes #36913
