    toolchain: gcc: backport patches to fix build with glibc 2.36
    
    glibc 2.36 changed the definition of enum fsconfig_command, it now
    collides with the same definition from sys/mount.h. Remove the include
    of linux/fs.h This still compiled with musl too.
    
    This backports a patch which is already in the stable branch of GCC 11
    and GCC 12.
