Now the cpu/x86/ provides a Makefile.x86_common and a Makefile.x86_pc. The former includes the common Makefile and adds legacy pc specific implementations (currently, drivers only) into the building context, while the latter has everything that defines the bootstrap of a x86 CPU. This commit also fixes platform/galileo/ so it includes the correct makefile - Makefile.x86_quarkX1000. Galileo uses a Quark X1000 SoC which is not an IBM Generic PC-like CPU, but it does provide most of a PCs peripherals through its "Legacy Bridge". Thus, it makes sense that QuarkX1000's Makefile includes code from the legacy_pc x86 cpu.
