+Subject: [PATCH] fix(aarch64): Move target #pragma after arm_neon.h include
+
+Fix per https://github.com/android/ndk/issues/1945
+
+If the pragma is done before the header include,
+in NDK 26 the attribute may apply to the functions in arm_neon.h
+
+Upstream-Status: Backport [https://github.com/jedisct1/libsodium/pull/1321]
