Hi,
Trying to cross build ARM fails in the following way on 8-stable:
8.2-STABLE FreeBSD 8.2-STABLE #1: Wed Jun 29 13:09:23 UTC 2011
make toolchain TARGET=arm
Is this perhaps also an issue in 9-current?
Any clues?

and you also said:
Tracing down the issue:
/usr/include/machine/endian.h
#define __byte_swap_int_var(x) \
__extension__ ({ register __uint32_t __X = (x); \
__asm ("bswap %0" : "+r" (__X)); \
__X; })
r0 looks like an ARM register passed to a non-arm assembler. I'm going to try:
Looks like you have an ARM compiler/assembler because the assembler
rejects the i386/amd64 "bswap" assembly command.
Does anyone remember if the cross compiler has the cross include paths
compiled into them or should there be a "-I" in the compile command to
correctly expand the "#include <machine/endian.h>" ? I thought the cross
path was compiled into the cross compiler.
You manually test the "cc" command with the included "-I" option.
