Hi. We are having some issues figuring out why one of our header files
fails to be installed properly into the SDK. The header file is
currently installed using a few lines in one of our recipe:

do_install_append() {
install -m 0644 ${S}/foo.h
Please don't do that.
I think just installing the foo.h into the ${D}${includedir} would do. And foo.h will end up in the FOO-dev package.
Make sure that the FOO package is in the IMAGE_INSTALL list, and then use 'bitbake <your-image-recipe> -cpopulate_sdk' command to populate the SDK.

foo.h ends up ok in our build/tmp/sysroots,
sysroots != SDK
The files under build/tmp/sysroots are usually generated by the do_populate_sysroot task of each recipe.

From my understanding, SDK is composed of two parts, the target part and the nativesdk part.
The nativesdk part is determined by the TOOLCHAIN_HOST_TASK.
And the target part is determined by the TOOLCHAIN_TARGET_TASK.
The reason that we could only ensure that FOO is in IMAGE_INSTALL is because in image.bbclass, we have:

The process of populating SDK is also composed of two parts, installing the target packages and installing the nativesdk packages. See populate_sdk_xxx.bbclass for more details.

but it does not make it to the SDK.
Is our do_install_append wrong in some way, does it have to be updated
to support SDK builds? Maybe it is wrong to use ${MACHINE} here?
