When you build a standard SDK using the
bitbake -c populate_sdk
, a default set of
packages is included in the resulting SDK.
The
TOOLCHAIN_HOST_TASK
and
TOOLCHAIN_TARGET_TASK
variables control the set of packages adding to the SDK.
If you want to add individual packages to the toolchain that runs on
the host, simply add those packages to the
TOOLCHAIN_HOST_TASK
variable.
Similarly, if you want to add packages to the default set that is
part of the toolchain that runs on the target, add the packages to the
TOOLCHAIN_TARGET_TASK
variable.
