Description:   Opened: 2006-10-25 22:12 0000 
ROOT=/blah/ PORTAGE_CONFIGROOT=/blah/ sudo emerge mdadm

/ is amd64
/blah/ is i686

gcc is invoked by mdadm's Makefile which - in this case - produces an error
(error: CPU you selected does not support x86-64 instruction set) as gcc is
invoked with -march=athlon-xp for the hosted environment.

Solution : to have Makefile invoke more specific gcc (i686-pc-linux-gnu-gcc in
this case)

Makefile seems to have support for setting $CROSS_COMPILE to specify prefix to
gcc.

Adding the following line below emake in the ebuild seems to give correct
results on amd64 and x86.


                CROSS_COMPILE="${CHOST}-" \
