[Buildroot] [PATCH 1/2] Add dependency on bash to gzip for runtime

[Jonathan Ben-Avraham]

From: Jonathan Ben Avraham <yba at tkos.co.il>

The GNU gzip package provides eleven executable files, all but one of
which are bash shell scripts. If we allow inclusion of gzip without
bash, then on executing commands such as lxc-checkconfig that actually
use these shell scripts, you will get errors like 'zgrep: not found',
even though the zgrep executable is in PATH.

This patch also sharpens up the help text and eliminates the claim to
provide gzcat.
