Well, the best documentation I can find is the thread discussing the
implementation:

http://www.x86-64.org/pipermail/discuss/2009-June/010546.html

and the testcase in binutils:

http://github.com/jiez/binutils/blob/master/ld/testsuite/ld-ifunc/lib.c

glibc seems to be using it in a few places in F12, so I can't imagine
it's too broken.  That said, I don't think it's the _recommended_
solution for Fedora yet.
