Replace libuuid with util-linux libuuid (and libblkid,
although we are not using libblkid right now).
This also requires a much larger coreboot cbfs, which was
fixed as part of issue #154.
This addresses multiple issues:
* Issue #63: initrd is build fresh each time, so tracked files do not matter.
* Issue #144: build time configuration
* Issue #123: allows us to customize the startup experience
* Issue #122: manual start-xen will go away
* Issue #25: tpmtotp PCRs are updated after reading the secret
* Issue #16: insmod now meaures modules
The populate-lib program was buggy on some systems and could accidentally
introduce unwanted libraries into the initrd. The Makefile now uses the
modules' $(module_libraries) variable to select which libraries should be
installed into the initrd.
Kernel modules are now stripped and installed using a similar system.
Pass in the --host argument to all of the various programs
that need to treat the configure scripts as cross compilation
targets.
This removes all dependencies on the host libc (issue #7)
and adds some tools to the initrd (cryptsetup #46).
This adds compilations modules for musl-libc and kernel-headers.
The entire initrd (busybox, cryptsetup, gpgv, kexec, etc) can be built
with the much smaller libc and it appears to work with chroot.
Library paths are not set correctly and files are installed into
heads/install to make them accessible to other modules. This prevents
the initrd from working without manual fixup; need to fix before
merging into master.
Build times have gone up since everything is being rebuilt more
often for some reason.
As part of issue #1, we should build all libraries and programs that we
deploy into the Heads initrd. This modifies the module configurations
for all of them to install into heads/install so that we can build
against them.
Add dmsetup, cryptsetup and veritysetup (issue #46).
Build gpgv 1.4 as a standalone tool (issue #23).
Modify populate-lib to use the install directory by setting
LD_LIBRARY_PATH (issue #35).
