This is very likely due to non-executable stack kernel patches
(Owl, grsecurity). Localedef program uses nested functions,
and gcc generates trampolines for calls, which in turn requires
stack to be executable. Owl patches (www.openwall.com) has
an option, "Emulate GCC Trampolines", and a program to control
whenever stack will be executable for a given program. Using
either of those cures the problem completely for me.
