Because of the following I've had to use
a ports binutils (such as
devel/powerpc64-binutils ) instead of the
system binutils in order to have a clang-based
powerpc64 world do a gcc 4.2.1 based "cross
build" (buildworld buildkernel).
This was from a clang-based buildworld buildkernel
powerpc64 FreeBSD context. It was an attempt to do a
gcc 4.2.1 "cross-compiler" based buildworld
buildkernel. It did not get very far before
(using one of several ld core files as an
example):

It appears that clang 5 outputs something
that the system ld does not expect, such that
htab->tls_get_addr==NULL is involved when
expecting_tls_get_addr==1 .

As I remember, back in clang 4 days I did
