X-Git-Tag: v2.6-dev1~82

BUILD: debug/cli: condition test of O_ASYNC to its existence

David Carlier reported a build breakage on Haiku since commit
5be7c198e ("DEBUG: cli: add a new "debug dev fd" expert command")
due to O_ASYNC not being defined. Ilya also reported it broke the
build on Cygwin. It's not that portable and sometimes defined as
O_NONBLOCK for portability. But here we don't even need that, as
we already condition other flags, let's just ignore it if it does
not exist.
