[oe] [meta-oe][meta-initramfs][PATCH] mkinitcpio: add new recipe

[Ioan-Adrian Ratiu]

This recipe provides a very flexible and useful tool for building
initfamfs'es from custom directories, having the ability to
auto-detect kernel module dependencies (for kernels built outside OE),
add custom build/runtime hooks, etc.

It can also be used on deployed systems (installed images on targets)
to re-generate the initramfs when a new kernel is installed from a
package feed.

+Subject: [PATCH 1/2] Makefile: don't check asciidoc output
+
+Don't use xmllint to validate the doc xsl schema because mkinitcpio's
+use of docbook is broken in a cross-compile environment (docbookx.dtd
+can't be found even though it's present in the recipe's sysroot).
+
+Investigating this is time consuming and this check is 99.9% benign
+anyway so it's safe to disable it.
+
+Upstream-Status: Inappropriate [embedded-specific]
