This looks like `registerConvertUBToLLVMInterface` or the `UBToLLVM` pass is missing in Flang. Should be a simple fix.

I can't reproduce this in my build:
```
$ build/bin/flang  -target powerpc64le-unknown-linux-gnu c.mlir
/usr/bin/ld: unrecognised emulation mode: elf64lppc
Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 elf_iamcu i386pep i386pe
flang-23: error: linker command failed with exit code 1 (use -v to see invocation)
```

Maybe you know off the top of your head which pass pass pipeline this test is exercising?
