Black screen with OVMF about roveros HOT 4 CLOSED

Cause may be related to OVMF/Qemu as using older gnu-efi code results in the same issue.
Running on MSI UEFI works correctly with master branch code and unreleased code.
Also tested with barebones UEFI code that does nothing but Print(L"test\n"); after InitilizeLib(...);

Edit: Black screen still occurs using new .efi files on real hardware. Cause is still undetermined

objdump of old and new EFI binaries shows no obvious issues or changes in the code or headers except 'endbr64' is absent. GDB does not appear to work with debugging EFI binaries as inline assembly functions used for debugging still execute despite GDB showing the memory being 0'd out. Using a cross compiler or gcc does not change the output. I will test changing gnu-efi make options.

The issue is caused by compiling the gnuefi code from source. Pasting in older binaries fixes the issue. The makefile will be updated and pre-compiled binaries will be added to the repo. My source code/makefile were not the cause of the issue.

To elaborate further, the elf_x86_64_efi.lds file was causing issues and #UD errors. A working version will be provided in an update that will be pushed tomorrow.
