I assume sgot rather than srelgot is intended for the first one, but.... 
 making this change horribly broke all execution tests for the 
GNU/Linux target.  The original code is returning sections in the output 
bfd, while the suggested changes return different sections owned by one 
of the input bfds.  Looking at the output from a simple test case with 
readelf, I could see that the associated PLTGOT and JMPREL entries in 
the dynamic section of the executable end up with null values when 
linked with the modified code.  This might be an indication of a bug 
elsewhere?  I'm still trying to sort it out....  hence the delay in 
posting a revised patch set.  :-(
