Description emaste 2015-04-14 16:09:03 PDT 
Required for the FreeBSD base system build.

GNU ld description:
       --dynamic-linker file
           Set the name of the dynamic linker.  This is only meaningful when
           generating dynamically linked ELF executables.  The default dynamic
           linker is normally correct; don't use this unless you know what you
           are doing.

A quick scan of the code shows up this is already implemented in HEAD, is it failing for you in some way?
Comment 2 emaste 2015-04-19 18:15:15 PDT 
Failing command line is:

/tank/emaste/src/freebsd/tools_bin/ld -Bdynamic -T /tank/emaste/src/freebsd/sys/conf/ldscript.amd64  --no-warn-mismatch  --warn-common --export-dynamic --dynamic-linker /red/herring  -o kernel.debug -X locore.o  cam.o cam_compat.o ...

It seems -dynamic-linker works, but --dynamic-linker (two dashes) does not.

r235282.
Comment 4 emaste 2015-04-19 19:18:29 PDT 
Update title based on fix: the form is --dynamic-linker /red/herring in the FreeBSD build; --dynamic-linker=/red/herring and -dynamic-linker /red/herring were already supported, but -- and no = was not.
