# Funny thing is if this is set to =error, some architectures will
# skip this flag even though the compiler flag check passes
# (e.g. ARC and Xtensa). So warning should be the default for now.

# Skip this for native application as Zephyr only provides
# additions to the host toolchain linker script. The relocation
# sections (.rel*) requires us to override those provided
# by host toolchain. As we can't account for all possible
# combination of compiler and linker on all machines used
# for development, it is better to turn this off.
#
# CONFIG_LINKER_ORPHAN_SECTION_PLACE is to place the orphan sections
# without any warnings or errors, which is the default behavior.
# So there is no need to explicitly set a linker flag.
