Or if you really need to call the linker directly without specifying search paths you could also install a shell script as /usr/bin/ld that passes the appropriate flags to /usr/bin/ld.lld?

I don't think ifdefs in the source code are a good idea. Cross linking should just work as expected. But you could look at the OS field in the first input ELF file to choose default config options/a different emulation for NetBSD.

The approach we are using in CheriBSD to differentiate between MIPS and CHERI pure-capability to either pass an explicitly `-m elf_btsmip_cheri_fbsd`/ `-m elf_btsmip_fbsd` or infer whether it is CHERI or MIPS based on the e_flags field of the first input file.
