Hi GNU ld experts!
This question is related to a StackOverflow discussion, how GNU ld handles architecture mismatches.
When the ELF objects are compiled in a different architecture than the target architecture from GNU ld.
Without passing GNU ld a target architecture, GNU ld detects the architecture in the ELF objects and
link the objects in a binary. If there are some mismatches with the object files, then GNU ld refuse the linking
with an error.
Issue #1
It isn't possible to pass the architecture to ARM GNU ld when passing the architecture via command line.
The option will not recognized and GNU ld abort with an error.
Issue #2
When trying to use a linker script and set the output architecture here, it leads in many errors
with mismatching EABI version. I have tried to find a option how to set the target EBAI version with
GNU ld, but currently didn't find the correct option, if this is possible.
On none-ARM architectures like AVR from Microchip (formerly Atmel) there are no issues with GNU ld
when setting the target architecture.
