I applied that patch, took your linker from here:

... and tried to build fdpp with this change:

(used LD_LIBRARY_PATH to locate proper libbfd)
It builds indeed but doesn't work.
I almost got used to my hack of extracting segments
with objdump, but it slows down the build twice, so
would be good to have that functionality sooner or later.
