[PATCH] eglibc: remove dependency of eglibc-utils on bash

[PATCH] eglibc: remove dependency of eglibc-utils on bash

[Paul Eggleton]

Adapt a patch from Peter Seebach <peter.seebach@windriver.com> to remove
the non-POSIX elements from the tzselect script, and add a separate
patch to work around a bug in the current version of busybox's awk
command. This replaces the /bin/bash reference in the script header with
/bin/sh and thus eliminates the dependency on bash picked up during
packaging.

Fixes [YOCTO #3551].

+tzselect: workaround bug in busybox awk
+
+busybox's version of awk in version 1.20.2 and lower doesn't support
+escape sequences in conjunction with the -F option. Use -v FS= instead
+as a workaround until the bug is fixed.
