Right, it was added later:
http://git.uclibc.org/uClibc/commit/extra/Configs/Config.in?id=a8dc90eaaa5e6474beac828558d969b1aafee4af

I don't know how often this file get updated?
 
BTW: These functions are only available for arm/mips/x86/x86_64.

So mongrel2/libsigsegv need to be fixed to these, when uClibc is
choosen.
