# --exclude-libs is not supported by lld, but is not required anyways.

# /fixed is passed by the build system when building with MSVC but not

# when building with GCC/binutils. The build system doesn't really support

# clang/lld, but apparently binutils and lld don't have the same defaults

# related to this. Unfortunately, /fixed is necessary for the stubs to be

# handled properly by the resource editor in NSIS, which doesn't handle

# relocations, so we pass the equivalent flag to lld-link through lld through

# clang.
