--- Comment #1 from Bryan Drewery <bdrewery at FreeBSD.org> ---
This isn't complete as GCC does not support -target. But it seems wrong to me
to need -target. I've never had problems cross-compiling with the external
compilers so far, though I may not have tried with clang.




LIB32CFLAGS+=   -B${CROSS_BINUTILS_PREFIX}

This -B flag is already being added via ${BFLAGS}.

Makefile.inc1:

.if defined(CROSS_BINUTILS_PREFIX) && exists(${CROSS_BINUTILS_PREFIX})
# In the case of xdev-build tools, CROSS_BINUTILS_PREFIX won't be a
# directory, but the compiler will look in the right place for its
# tools so we don't need to tell it where to look.
BFLAGS+=        -B${CROSS_BINUTILS_PREFIX}
.endif

Makefile.libcompat:

LIBCOMPATCFLAGS+=       ${LIBCOMPATCPUFLAGS} \                 
                        -L${LIBCOMPATTMP}/usr/lib${libcompat} \
                        --sysroot=${LIBCOMPATTMP} \            
                        ${BFLAGS}                              
                       ^^^^^^^^^^
