Force production of ELF hash table

[John Cronin]

Hello,

I am using ld to link an OS kernel.  The kernel produced is a statically 
linked executable file but supports dynamic modules.  I would like to 
use the hash table functionality of ELF files to quickly look up symbols 
within the statically linked kernel file for dynamically loading the 
modules however cannot work out how to ask ld to add the hash table to 
non-shared outputs.  Is it possible?  I see from 
http://elinux.org/images/1/18/C_AMOROSO_Fast_lkm_loader_ELC-E_2009.pdf 
that the embedded linux guys have had to write their own tool (ksymhash) 
to modify the vmlinux image after linking but I was wondering whether 
there was a way to ask ld to do it for me.  I am using the x86_64-elf 
target.

Regards,
John.
