adt-installer: allow installation of other machines
Currently, adt-installer allows only the installation of qemu target
sysroots.
The changes in this patch do the following:
* add a new setting in adt-installer.conf (YOCTOADT_TARGET_MACHINE) for
each target architecture. For example, for arm we can choose to use a
qemuarm sysroot or a beagleboard sysroot. By default, only the qemu
target sysroots are selected (current behavior);
* change adt_installer scripts to allow installing the correct
meta-environment package for the selected machine;
* remove some left-over commented lines;
* use packagegroup-cross-canadian-${MACHINE} when installing the cross
canadian packages instead of doing it separately for each package;
* change the opkg config files in order to be able to find the
packagegroup package, which is allarch;
