[OE-core] [RFC 0/1] adt-installer: add support for relocatable SDK

[Laurentiu Palcu]

Hi all,

This patch will add relocatable SDK support to adt installer. That is, the user
can provide an install folder, different than the default one (usually
/opt/${DISTRO}/${SDK_VERSION} and the binaries will be automatically relocated.

Why RFC? Well, adt_installer uses opkg in order to populate the SDK rootfs. If
the user wants to install, for example, x86_64 Poky SDK under, say,
/home/user/some/directory, he/she will end up with this directory structure:
/home/user/some/directory/opt/poky/1.2+snapshot/sysroots/x86_64-pokysdk-linux/...

The idea is to strip opt/poky/1.2+snapshot from this structure and end up with:
/home/user/some/directory/sysroots/x86_64-pokysdk-linux/...

With the meta-toolchain stuff it was easy because tar has the feature to strip
a number of components from file names on extraction and all was fine. But opkg,
doesn't... Not that I know of.

So, I had two options:
	- hard way: patch opkg to be able to support this. Implementation could take
	  some time and the feature will be rarely used in real-life;
	- easy way: the solution I chose: after opkg finishes installation of the
	  entire directory structure, move sysroots directory (together with the
	  setup scripts) to the location we want and then get rid of the
	  ./opt/poky/1.2+snapshot/ tree, which is empty anyway.

Any comments?

Thanks,
Laurentiu
