[PATCH] Gracefully handle incompatible locale data

[Ludovic Courtès]

With libc 2.22 people are starting to realize that libc does not
guarantee that it can load locale data built with another libc version,
but they learn it the hard way:

  loadlocale.c:130: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_COLLATE) / sizeof (_nl_value_type_LC_COLLATE[0]))' failed.

This patch changes such conditions to return EINVAL instead of aborting.

WDYT?

Thanks,
Ludo’.

	* locale/loadlocale.c (_nl_intern_locale_data): Change assertion
	on CNT to a conditional jump to 'puntdata'.
