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.
