make kexec work with the modular build

Generate a fake EBDA with kexec, removing the need for a custom xen (#227) This modifies the segment at 0x0 so that it contains enough of a fake Extended BIOS Data Area at addresses 0x40e and 0x413 that Xen can correctly locate its trampoline code. Since custom Xen is no longer required, we can remove the module, the patches and all of the references to it in the board definition files.

Download and build almost all dependencies. 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).

kexec_configure := ./configure \
Define $(CROSS_TOOLS) to ensure reproducible builds (issue #173) Each of the submodule configuration files defined a subset of the cross compiler tools that it used and many were picking up the system `ar`, `nm`, `strip, `ld`, etc. They all now use a `Makefile` macro that defines the path to the proper cross compiler tools. For ones that need the tools, but not the musl-libc gcc, there is $(CROSS_TOOLS_NOCC) that is all of them without gcc. This is for musl-libc itself, as well as xen and the Linux kernel.

$(CROSS_TOOLS) \
Working build with musl-libc cross compiler (issue #77). 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).

Build GNU make-4.2 if the system make is the wrong version (issue #88). Change all of the builds to use $(MAKE) instead of the /usr/bin/make. Download and build GNU make-4.2 if the wrong version is installed on the system. Re-invoke build/make-4.2/make with the target that was passed in once the correct make has been built.

Build initrd tools with musl-libc (issue #77). 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.
