Config.in: move toolchain menu before build options

Many of the build options depend on the toolchain configuration. In
addition, it's pretty logical that you select first target architecture,
then the toolchain, and only then things like debug and pic/pie.
Therefore, move the "Toolchain" menu before the "Build options" menu
instead of after.
