=46rom share/mk/bsd.README :
LDFLAGS Additional loader flags. Passed to the loader via CC,
since that's used to link programs as well, so loader
specific flags need to be prefixed with -Wl, to work.
But the following 3 powerpc (non-64) examples do not use the -Wl, =
notation:
> LDFLAGS+=3D -m elf32ppc_fbsd
> /usr/src/sys/boot/ofw/Makefile.inc
> LDFLAGS+=3D -m elf32ppc_fbsd
> /usr/src/sys/boot/uboot/Makefile.inc
> LDFLAGS+=3D -m elf32ppc_fbsd
> /usr/src/sys/boot/powerpc/Makefile.inc
In fact I get errors such as (for that last one when using powerpc64-gcc =
via powerpc64-xtoolchain-gcc, executed on a powerpc64):
> powerpc64-portbld-freebsd11.0-gcc: error: elf32ppc_fbsd: No such file =

I do not know if the space between -m and elf... creates a problem for =
-Wl, use or not. I would guess that
-Wl,-m,elf32pcc_fbsd
is the proper notation for putting the space through to the ld variant =
used. But I=E2=80=99m not to the point of testing the behavior of that =
yet.
i386 seems to have a similar example, although I=E2=80=99m not using =
such a FreeBSD environment.
> LD_FLAGS+=3D -m elf_i386_fbsd
> /usr/src/sys/boot/i386/Makefile.inc
(This note is shorter in part because figured out more context than I =
had last time.)
