As the ability to generate non-Linux based components, such as
baremetal, FreeRTOS, Zypher, etc, exist. There is a need for a way
to take components as specific to a given OS.
This is especially important in a multiconfig build where you may be
targeting different OSes which different sets of recipes in a common
set of layers.
Setting a default of (matching bitbake.conf's default TARGET_OS):
COMPATIBLE_OS ?= "linux${LIBCEXTENSION}${ABIEXTENSION}"
Will allow all existing recipes to be tagged as Linux specific, so
only non-Linux recipes would need to be tagged with specific
compatibility.
For a baremetal recipes, the following was used to test this code:
COMPATIBLE_OS = "elf"
COMPATIBLE_OS_arm = "eabi"
