The build failed in multiple configurations. First, the native and
nativesdk was using the host compiler and was pulling host libraries
into the build. Second, the target configuration was attempting to
execute tools/bin2header tool on host, which is compiled for target,
to generate license header file that is not used by tools.
This patch changes the EXTRA_OEMAKE to address these issues, to build
both native and target builds with the correct compilers and correct
sysroots. Moreover, this patch removes the CONFIG_CMD_LICENSE from
tools build, thus disabling the execution of target tools/bin2header.
