Add support to generate locale data
In order to use locale support on a Linux system, you need locale data to be present: * on a (e)glibc based system, this data is typically in the /usr/lib/locale/locale-archive file, which can be created and extended using the localedef program * on an uClibc based system, the set of supported locales is defined at build time by an uClibc configuration option. This patch implements generating locale data for the following cases: * Internal toolchain * External toolchain based on (e)glibc. uClibc external toolchains are not supported, because with uClibc, the set of supported locales is defined at build time. CodeSourcery and Linaro toolchains have been tested, Crosstool-NG toolchains are believed to work properly as well. * Toolchains built using the Crosstool-NG backend, but only (e)glibc toolchains. This feature was runtime tested with internal uClibc toolchain, CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a simple C program that shows the data and a gettext translated message. Note that this option differs from the "purge locales" option, which is responsible for removing translation files and other locale stuff installed by packages. At some point in the future, we may want to clarify the respective roles of those options.
