                OS: Any
            Status: New

FreeBSD's migration to a full permissively-licensed modern tool chain is in
progress. This PR will track the work necessary to move away from the obsolete
GNU ld.bfd 2.17.50 to lld or external toolchain for all architectures.

LLD status:

** x86 **

amd64: complete, lld is the bootstrap and system linker
A small number of ports issues remain, tracked in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214864

i386: proof of concept demonstrated with lld as bootstrap linker but some new
issues have appeared, tracked in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225128

** Arm **

arm64: complete, lld is the bootstrap and system linker

armv7: proof of concept demonstrated, one known issue tracked in
https://bugs.llvm.org/show_bug.cgi?id=36009

armv6 and lower: lld is currently not suitable

** MIPS **

The multi-GOT patch was finally committed upstream in
https://reviews.llvm.org/rL334390. Proof of concept demonstrated using patched
lld as MIPS linker.

** PPC **

LLD currently not functional as bootstrap linker

** sparc64 **

LLD lacks sparc64 support

** RISC-V **

LLD lacks usable RISC-V support
