libc-package.bbclass, eglibc, glibc: enable locales generation using cross-localedef

Browse Source 
Along with qemu this provides another option to generate locales for
[e]glibc. The new method is to use cross-localedef with appropriate arch
specific parameters.

The cross-localedef method is found to be 15 times faster than qemu's
emnualted method.

LOCALE_GENERATION_WITH_CROSS-LOCALEDEF : This is new config variable
introduced to selet qemu or cross-localedef method for locale generation.

Thanks to Mark Hatle from Windriver for providing the rich
information for cross locale generation.
