package/glibc: drop dependency of utilities on bash

package/glibc: drop dependency of utilities on bash

The dependency was added because ldd uses bash-specific syntax to
localize messages. Add a post-patch hook, instead, to replace the
occurrences of $"foo" by "foo", simply, so the code becomes POSIX
sh compliant if bash is not selected.

Also set the configuration environment accordingly to replace the
/bin/bash hashbang by /bin/sh.
