Re: [PATCH] Cygwin: define OUTPUT_FORMAT and SEARCH_DIR for AArch64

[Radek Barton via Cygwin-patches]

Hello.

The following:

diff --git a/winsup/cygwin/cygwin.sc.in b/winsup/cygwin/cygwin.sc.in
index 5007a3694..e71e0189c 100644

+#elif __aarch64__

breaks Fedora build 
(https://github.com/Windows-on-ARM-Experiments/newlib-cygwin/actions/runs/16051682177).
