Brad 46eef33b89 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:

ld: multiboot.o: relocation R_X86_64_16 can not be used when making a shared object; recompile with -fPIC

Jan Kiszka 0d6b9cc742 signrom: Rewrite as python script
Now that we have a hard dependency on python anyway, we can replace the
slow shell script to calculate the option ROM checksum with a fast AND
portable python version. Tested both with python 2.7 and 3.1.

This imports and builds the original VAPIC option ROM of qemu-kvm.
Its interaction with QEMU is described in the commit that introduces the
corresponding device model.

Jan Kiszka 6fbcef296a optionroms: Silence intermediate file removal
The build process of optionroms spits out an "rm ..." line. Moreover, it
removes all .o files that can be handy for debugging purposes. So
disable automatic intermediate removal.

Paolo Bonzini 076d247142 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.

Alexander Graf 57a46d0579 Convert linux bootrom to external rom and fw_cfg
We already have a working multiboot implementation that uses fw_cfg to get
its kernel module etc. data in int19 runtime now.

So what's missing is a working linux boot option rom. While at it I figured it
would be a good idea to take the opcode generator out of pc.c and instead use
a proper option rom, like we do with multiboot.

So here it is - an fw_cfg using option rom for -kernel with linux!

Thomas Monjalon fc3baad7bf restore CFLAGS check for conflict and fix recursive CFLAGS issue
cc-option uses more make-syntax to replace the shell "if/else".

Issue with recursive += is fixed by doing the first assignment

Juan Quintela a558ee1776 Rename CPPFLAGS to QEMU_CFLAGS
Now we have to variables: QEMU_CFLAGS: flags without which we can't compile
CFLAGS: "-g -O2"

We can now run:

make CFLAGS="-fbar" foo.o
make CFLAGS="" foo.o
make CFLAGS="-O3" foo.o

And it all should work.

Alexander Graf 253d0942fa 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.
