commit: https://git.buildroot.net/buildroot/commit/?id=44d17dd128164cfe7870f5bef279e273ba59f83d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Using the GZIP environment variable to pass gzip options is
deprecated, and therefore we are going to remove the "GZIP = -n"
definition from the main Buildroot Makefile. In preparation for this,
we explicitly add the -n argument to the gzip call in fs/common.mk to
ensure reproducibility.
