This patch simplifies seabios cross-builds on !x86 platforms. It adds a CROSS_PREFIX variable which is used to set CC, LD & friends to the cross build binaries. It also moves the common command definitions up in the Makefile to make sure CC is set correctly when probing compiler flags using $(call cc-option ...)
