OK.  This is Working As Advertised.  Machines that don't actually support
IFUNC should have a sysdeps/.../configure that does:
libc_cv_asm_gnu_indirect_function=no
...which is what I said in the original posting.

If you want to work on souping up an automatic configure test, more power
to you.  But that still won't tell you whether the dynamic linker support
is actually implemented.


Thanks,
Roland
