Build time configuration for startup scripts and modules. 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 2017-03-31 15:18:46 +00:00			`modules-y += busybox`

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. 2016-12-29 23:23:08 +00:00			`busybox_target := \`
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 $(CROSS_TOOLS_NOCC) that is all of them without gcc. This is for musl-libc itself, as well as xen and the Linux kernel. 2017-04-08 17:23:34 +00:00			`$(CROSS_TOOLS) \`
