The Gold linker defaults to the use of --new-dtags which uses DT_RUNPATH instead of DT_RPATH. In previous version of binutils, --new-dtags would write set both DT_RUNPATH and DT_PATH, but not anymore. The problem is that neither NetBSD nor OpenBSD runtime linkers properly handle it AFAICT. Use macros to make DT_RPATH get set when -rpath switch is used so that linked libraries can get found on these platforms. Similarly, it appears that DT_INIT_ARRAY tags are also not handled by rtld, so don't use these tags by default otherwise C++ will not link on these platforms. The copy-as-needed attribute has been left at its binutils default of --no-copy-dt-needed. This has been the default since binutils 2.22.

The NetBSD and OpenBSD real-time linkers do not understand DT_RUNPATH
|
|
or DT_INIT_ARRAY. The current gold defaults are not suitable for them.
|
|
The last couple of DragonFly and FreeBSD releases do support these tags.
