* fat-setup.h: Disable use of ifunc, since it breaks dlopen with
RTLD_NOW.

/* Disable use of ifunc for now. Problem is, there's no guarantee that
one can call any libc functions from the ifunc resolver. On x86 and
x86_64, the corresponding IRELATIVE relocs are supposed to be
processed last, but that doesn't seem to happen, and its a
platform-specific feature. To trigger problems, simply try dlopen
("libnettle.so", RTLD_NOW), which crashes in an uninitialized plt
entry. */
