Hi,=20
Im trying to fix cross-compiling for arm architecture using clang. I =
added following patch:

# bootstrap-tools stage
BMAKEENV=3D INSTALL=3D"sh ${.CURDIR}/tools/install.sh" \
PATH=3D${BPATH}:${PATH} \
Now it compiles up to stage 4.2 where it fails (). For some reason =
-ccc-host-triple is not passed to compiler, but it is defined in CC.=20
Is CROSSENV right place to add -ccc-host-triple ?
Any hints?
Thanks,
Damjan
