More evil.  This feature is actually within spec.  The specification say that
a program has either to include the required relocation information or to
be fully relocatable.  With ECOFF ...  I solved that by using SVR4 PIC code
which I squeeze into ECOFF binaries using a small converter program
included with 0.27.1.  Don't even dare to dare to think about eventually
considering the use of binutils for linking ELF/PIC code into ECOFF/PIC.
You'll find zillions of interesting bugs.
