-Subject: [PATCH] build: Enable 64bit off_t on 32bit glibc systems
-
-Pass -D_FILE_OFFSET_BITS=64 to compiler flags on 32bit glibc based
-systems. This will make sure that 64bit versions of LFS functions are
-used e.g. lseek will behave same as lseek64. Also revert [1] partially
-because this added a cmake test to detect lseek64 but then forgot to
-pass the needed macro during actual compile, this test was incomplete too
-since libc implementations like musl has 64-bit off_t by default on 32-bit
-systems and does not bundle -D_LARGEFILE64_SOURCE [2] under -D_GNU_SOURCE
-like glibc, which means the compile now fails on musl because the cmake
-check passes but we do not have _LARGEFILE64_SOURCE defined. Moreover,
-Using the *64 function was transitional anyways so use
--D_FILE_OFFSET_BITS=64 instead
