Multiboot build system v4 In order to build the multiboot option rom, we need a Makefile and a tool to sign the rom with. Both are provided by this patch and mostly taken from the extboot source, written by Anthony Liguori. Once built, the resulting binary gets copied to pc-bios automatically. Building also occurs automatically when on an x86 host. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Use vpath directive The vpath directive has two advantages over the VPATH variable: 1) it allows to skip searching of .o files; 2) the default semantics are to append to the vpath, so there is no confusion between "VPATH=xyz" and "VPATH+=xyz". Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper macro to append one or more directories to the vpath.

Fix QEMU build on OpenBSD on x86 archs This resolves the build issue with building the ROMs on OpenBSD on x86 archs. As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the whole OS/packages and so forth. The ROMs need to have PIE disabled. Check in configure whether the compiler supports the flags for disabling PIE, and if it does then use them for building the ROMs. This fixes the following buildbot failure: >From the OpenBSD buildbots..
