Okay, sounds good.

I spent yesterday reading libelf documentation/examples. I should be able
to finish this task today.
It turns out that libelf cannot/does not update any headers when the data
for a section is changed so it will have to be done manually.
My idea is to create two "skeleton" elfs with missing .text sections that
the application will patch.
First the ISA microcode will be patched into the second elf then the second
elf will be patched into the first.
Regards,
Daniel
