4-Subject: [PATCH] cmake: Enable 64bit off_t on 32bit glibc systems
5-6-Pass -D_FILE_OFFSET_BITS=64 to compiler flags on 32bit glibc based
7-systems. This will make sure that 64bit versions of LFS functions are
8-used e.g. seek will behave same as lseek64. Also revert [1] partially
9-because this added a cmake test to detect lseek64 but then forgot to
10-pass the needed macro to actual compile, this test was incomplete too
11-since libc implementations like musl has 64bit off_t by default on 32bit
12-systems and does not bundle[2] -D_LARGEFILE64_SOURCE under -D_GNU_SOURCE
13-like glibc, which means the compile now fails on musl because the cmake
14-check passes but we do not have _LARGEFILE64_SOURCE defined. Using the
15-*64 function was transitional anyways so use -D_FILE_OFFSET_BITS=64
16-instead
