Subject: [PATCH] Do not use LFS64 functions on linux/musl

On musl, off_t is 64bit always ( even on 32bit platforms ), therefore using
LFS64 funcitons is not needed on such platforms. Moreover, musl has stopped
providing aliases for these functions [1] which means it wont compile on
newer musl systems. Therefore only use it on 32bit glibc/linux platforms
and exclude musl like cygwin or OSX
