Add --always flag to "git describe" command to get a build identifier
even if one checks out the repo with a depth parameter that prunes out
the last tagged version.

Recent versions of gcc will sometimes place conditional checks in the
code prior to setting up the function's stack frame. Handle this case
correctly.

Some linkers verify that sections have a start address that is aligned
with the minimum alignment of that section. Add extra padding to the
".text" section to ensure it is always aligned with the maximum
alignment of any section placed in ".text".

exceptions that are known to be possible.

If building from an official tarball and EXTRAVERSION info is
provided, then consider the build to be "clean" (don't include
hostname/build timestamp). This is done on the expectation that
EXTRAVERSION will have enough information to allow developers to find
the builder and build environment should a defect be reported, and
therefore the hostname/timestamp is not necessary.

There is some variation in version strings between various tool chain
builds. Make the version tool scan more permissive to attempt to
handle these variations.

If the build environment looks "clean" then don't add the build
hostname or build time to the version string. This makes the default
build string reproducible across builds.

Convert the script to generate the build version from a shell script
to a python script.
Remove the ability to override the version at build time via "make
VERSION=xyz". Replace it with ability to add extra version
information at build time via "make EXTRAVERSION=xyz".

Add a build option to explicitly set the version information compiled
into the seabios and seavgabios binaries. This may assist in
reproducible builds or to better link builds to distribution packages.
If the new "VERSION=" parameter is not provided then the default build
version remains unchanged.

I've been successfully using SeaBIOS as secondary bootloader. In more details
I have GRUB2-as-payload in flash together with coreboot. SeaBIOS binary is on
the HDD and loaded by GRUB when needed. This has an unfortunate consequence
that I have to keep vga oprom in flash even if usually I boot without it. This
patches makes bios.bin.elf multiboot executable with files passed as modules.
Example:
menuentry "SeaBIOS (mb)" --unrestricted {
root=ahci0,2
multiboot /bios.bin.elf
module /vgabios_x230.rom name=pci8086,0166.rom
}
the parameter name= specifies under which name SeaBIOS will see it.

Emulate the "leal" instruction so that the vgabios can run on older
