xcompile: Add a way to specify -march=i586
Instead of instructing users to edit xcompile when they want to build
a quark platform, give the build a way to set -march=586 so that
the quark code will build correctly. The Quark processor does not
support the instructions introduced with the Pentium 6 architecture.
