-Subject: [PATCH] disable fseeko usage on 32-bit Android older than API 24
-
-feesko is not supported on 32-bit Android older than API 24 [1].
-Older SDKs would allow the call but the 64-bit off_t was not accurate.
-With the NDK26 the call is hidden in that case and calling fseeko() results in a compilation error.
