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. jadamcze@utas.edu.au 2006-10-25 22:26:12 0000 Adding the following line below emake in the ebuild seems to give correct results on amd64 and x86.
