[Buildroot] [PATCH 04/20] Detect early if an UTF-8 locale is needed

Check in toolchain/dependencies/dependencies.sh if an UTF-8 locale is
properly present on the system before trying to build a locale enabled
toolchain. As this test is only needed when a locale enabled toolchain
is going to be built, we pass the configuration file path to the
dependencies.sh script so that it can grep for the current value of
various options.
