[PATCH 1/19] Kconfig I18N: sublocale

[Egry Gábor]

The external store of .mo files are unfrendly and binary .mo 
files are ungly in the source code. This patch creates a temporary 
locale directory on build time in <kernel_source>/.locale/ 
directory instead of /usr/share/locale/ and compiles the 
necessary source language files from the <kernel_source>/po/ directory.

Without installed gettext package the configuration interfaces remain 
in english.

This patch contains too a hook for additional patches. If one or more 
po/*-po directories exist (ex. po/grsecurity-po/) then the content of 
them will merged into the temporary locale directory. In this way the 
configuration interface of external patches will be localisable.
