The oldest kernel version for nios2 is 3.19.0, set it so, otherwise
qemu-nios2 -r ${OLDEST_KERNEL} fails with "FATAL: kernel too old"
message from glibc.

The nativesdk sysroot is already being passed in
via --sysroot option, adding -isystem is redundant
and more so it causes build failures with gcc-6
since it messed with internal search order for system
includedirs

The official download servers www.[country].apace.org only host the latest
release, so the URL is only valid when the recipe is fully up to date.

In the general case this isn't a problem as our mirror list includes
archive.apache.org, but the upstream URI checking (the checkuri task) fails as
that explicitly doesn't use the mirrors.

* Use "??=" in bitbake.conf to set LICENSE, so that it can overrided by
  packagegroup.bbclass and recipes.

* Use "?=" to set LICENSE and LIC_FILES_CHKSUM to MIT by default
  in packagegroup.bbclass, this won't impact any packagegroup recipes
  which use non-MIT license, since they can be overrided by the recipe.

We never want checksum to vary depending on whether we calculate them
in server or worker context, that would make no sense. This was happening
in do_rootfs tasks since they reference the BB_WORKERCONTEXT variable.

Whitelist the variable to avoid this class of problem.

Tweak DEBUG_FLAGS to use "/usr/src/debug/${PN}/${EXTENDPE}${PV}-${PR}"
as source target path in DWARF. While use gdb to debug binary, it could
work with sources in dbg package.

While -fdebug-prefix-map is used for compiling, we do not need invoking
debugedit to edit DWARF at do_package time, but list where sources files
are.

The copydebugsources uses the list to copy sources to dbg package. It
works whether -fdebug-prefix-map used or not.

The new value is more general and better reflects what having the feature really means.
Introspection data, then, is built only if 'gobject-introspection-data' is in
DISTRO_FEATURES and 'qemu-usermode' is in MACHINE_FEATURES.

We don't need these variables incorporated in the config hash (i.e. we
don't need to reparse if they change).

This fixes an issue with the extensible SDK where the cache generated
at installation time not to be used afterwards due to the way we're
allowing through the proxy variables into the install environment (such
that they get set to "" if not set externally).
