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.
