image.bbclass: Unconditional includes of populate_sdk_ext fails
populate_sdk_ext requires uninative support, which is only available on
glibc based SDKMACHINES. For instance, when using mingw32 a dependency
error will occur:
NOTE: Runtime target 'nativesdk-glibc' is unbuildable, removing...
ERROR: Required build target 'core-image-minimal' has no buildable providers.
Missing or unbuildable dependency chain was: ['core-image-minimal', 'uninative-tarball', 'nativesdk-glibc']
This is dues to populate_sdk_ext.bbclass having:
do_populate_sdk_ext[depends] += "buildtools-tarball:do_populate_sdk uninative-tarball:do_populate_sdk"
addtask populate_sdk_ext
Since bitbake can't determine for dependency resolution if the task is going
to be run yet, it blows up and says it simply can't be resolved.
Workaround this problem by making the inherit conditional on the SDK_OS
containing 'linux'.
