Improve handling of 'all' architecture recipes and their interaction with sstate

The existing PACKAGE_ARCH = "all" mechanism of sharing packages is problematic
with sstate since there are a variety of variables which have target specific
values and the sstate package therefore correctly changes signature depending
on the MACHINE setting.

This patch creates a new "allarch" class which sets:

PACKAGE_ARCH = "all"

(as per the existing convention)

INHIBIT_DEFAULT_DEPS = "1"

(since its not target specific and therefore can't depend on the cross
compiler or target libc)

TARGET_ARCH = "all"
TARGET_OS = "linux"
TARGET_CC_ARCH = "none"

(since these variables shouldn't change between the different packages and
target compiler flags shouldn't be getting used)

PACKAGE_EXTRA_ARCHS = ""

(since we shouldn't be depending on any architecture specific package architectures)

Not all PACKAGE_ARCH = "all" recipes can use this class since some run configure
checks on the compiler. This means they have target specific components and therefore
the "all" classification is incorrect.
