+Subject: [PATCH] Use open instead of open64
+
+glibc is providing open64 and other lfs64 functions but musl aliases
+them to normal equivalents since off_t is always 64-bit on musl,
+therefore check for target env along when target OS is linux before
+using open64, this is more available. Latest Musl has made these
+namespace changes [1]
+
+There is no need for using LFS64 open explicitly as we are only using it
+for opening device files and not real files
+
