Linker Error related to PIE

[nstarke]

Hello,

I am attempting to build xnu-qemu-arm64 from the repository diff file and I am running into a linker error:

[...]
  BUILD   pc-bios/optionrom/multiboot.img
ld: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?)
make[1]: *** [Makefile:52: multiboot.img] Error 1
make: *** [Makefile:576: pc-bios/optionrom/all] Error 2
make: *** Waiting for unfinished jobs....

This is on ubuntu 21.04 with the following ld version information:

$ ld --version
GNU ld (GNU Binutils for Ubuntu) 2.36.1

The linker error is caused by something related to the optionrom directory (pc-bios/optionrom/Makefile).

I don't think the optionroms are necessary to get this project working, though I definitely could be wrong. I am preparing a pull request with an updated diff that disables compiling of the optionroms. I did not see a flag in ./configure that would enable me to do this.

Pull request forthcoming.
