I'd rather remove the ifdef altogether. If they're available on those
three architectures, they're quite likely available on arm64 as well. And
I just checked; the arm64 version of msvcrt.dll also does contain these
symbols.
The reason for this discrepancy to begin with, was that most of these def
files have started from dumps of different versions of msvcrt.dll; the
arm32 dump was made from a much newer version that the other ones.
For arm64, we've not really done any bulk import from dumps at all. When
arm64 became relevant, we instead unified the common similar bits from
i386/x86_64/arm32 (leading to a shared file with these symbols only
available for arm32, as that was what it looked like in the 3 separate
dumps before that) and concluded that whatever is common/shared between
them, also should exist similarly for arm64.
