source: clfs-sysroot/patches/glibc-2.6.1-cross_hacks-1.patch@ e48b96a

Submitted By: Joe Ciccone <jciccone@linuxfromscratch.org>
Date: 2006-11-26
Initial Package Version: 2.5
        Rediffed against 2.6 by Joe Ciccone
Origin: Joe Ciccone
Upstream Status: Unknown
Description: Adds native compile support to the build system then uses that
             support to build zic-native, for installing timezone info,
             rpcgen-native, for building librpcsvc.a, and localedef-native,
             for creating the locale-archive.
