On WSL 1 trying to allocate memory close to the binary by supplying a hint fails with ENOMEM for unclear reason. Some reports suggest that this might be related to the alignment of the hint but aligning it by 64Kb does not make the issue go away in our experiments. Instead just retry without any hint. Fixes https://github.com/dart-lang/sdk/issues/54587 TEST=manually under WSL 1 Change-Id: I0adf997fbf76e470a57da00f5ce7a26bb50706f7 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/345802 Commit-Queue: Slava Egorov <vegorov@google.com> Reviewed-by: Alexander Aprelev <aam@google.com>
