Hi,
I tried to cross compile latest armv7 src and I experienced a few
problems.

Maybe I was doing something wrong or maybe the patch will make sense -
below are the changes I had to apply to make it build calling:

make -f Makefile.cross TARGET=... CROSSDIR=... cross-dirs
make -f Makefile.cross TARGET=... CROSSDIR=... cross-tools
make -f Makefile.cross TARGET=... CROSSDIR=... cross-distrib

Unfortunately, its completely untested - I dont have any supported armv7
board yet but Ill try to get one.

The first issue was:
===> ld.so/ldconfig

arm-unknown-openbsd7: error: linker command failed with exit code 1 (use -v to see \
                invocation)
*** Error 1 in libexec/ld.so/ldconfig (<bsd.prog.mk>:126 'ldconfig')

The other was a linker issue - linking against host platform libraries.
Probably wont even show up if platform and target match. 
LDADD was used where DPADD should be used?

Maybe it should go to tech@ but Id like to verify the issue exists at
all and its not PEBCAK case.

BR,
