[makefile] Add support for multiple build platforms
Allow for the build CPU architecture and platform to be specified as part of the make command goals. For example: make bin/rtl8139.rom # Standard i386 PC-BIOS build make bin-efi/rtl8139.efi # i386 EFI build The generic syntax is "bin[-[arch-]platform]", with the default architecture being "i386" (regardless of the host architecture) and the default platform being "pcbios". Non-path targets such as "srcs" can be specified using e.g. make bin-efi srcs Note that this changeset is merely Makefile restructuring to allow the build architecture and platform to be determined by the make command goals, and to export these to compiled code via the ARCH and PLATFORM defines. It doesn't actually introduce any new build platforms.
