When compiling older GCC versions in newer machines, libsanitizer does not compile, showing a error: multiple definition of 'enum fsconfig_command' (e.g.https://github.com/llvm/llvm-project/issues/56421).
This is because starting from Glibc 2.36, it is not possible to include both "linux/fs.h" and "sys/mount.h".
We can apply a patch, similar to the one in https://reviews.llvm.org/D129471 , but with the extension and lines changed to match the file. This is also similar to the upstream fix.
