-      The LLVM Project is a collection of modular and reusable compiler and
-      toolchain technologies. Despite its name, LLVM has little to do with
-      traditional virtual machines. The name "LLVM" itself is not an acronym; it
-      is the full name of the project.
-      LLVM began as a research project at the University of Illinois, with the
-      goal of providing a modern, SSA-based compilation strategy capable of
-      supporting both static and dynamic compilation of arbitrary programming
-      languages. Since then, LLVM has grown to be an umbrella project consisting
-      of a number of subprojects, many of which are being used in production by
-      a wide variety of commercial and open source projects as well as being
-      widely used in academic research. Code in the LLVM project is licensed
-      under the "Apache 2.0 License with LLVM exceptions".

-
-On musl libc the fopen64 and fopen are the same thing, but for
-compatibility they have a `#define fopen64 fopen`. Same applies for
-fseek64, fstat64, fstatvfs64, ftello64, lstat64, stat64 and tmpfile64.

-Subject: [PATCH] cmake: 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. seek 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 to actual compile, this test was incomplete too
-since libc implementations like musl has 64bit off_t by default on 32bit
-systems and does not bundle[2] -D_LARGEFILE64_SOURCE 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. Using the
-*64 function was transitional anyways so use -D_FILE_OFFSET_BITS=64
-instead
