EXTERNAL_TOOLCHAIN + systemd: Unable to compile

EXTERNAL_TOOLCHAIN + systemd: Unable to compile

[Parthiban]

Dear All,

Am trying to use external=arm toolchain with scarthgap mainline together with systemd as INIT_MANAGER.
With my current understanding, as systemd mandates "usrmerge" DISTRO_FEATURES, both the destination
and source path changes to same and resulted in the below error.

| mv: 'build/tmp/work/cortexa53-poky-linux/external-arm-toolchain/12.2.Rel1/image/usr/lib/libasan.a' and 'build/tmp/work/cortexa53-poky-linux/external-arm-toolchain/12.2.Rel1/image/usr/lib/libasan.a' are the same file

From conf/local.conf:
DISTRO_FEATURES:append = " systemd usrmerge "
EXTERNAL_TOOLCHAIN = "/opt/tooling/aarch64"
TCMODE = "external-arm"

External toolchain version: gcc version 12.2.1 20221205 (Arm GNU Toolchain 12.2.Rel1 (Build arm-12.24))

When I try to ignore this error "|| true" or skip it, packages compilation failed with libc linking.

Is it possible to use external-arm + systemd with scarthgap?

This is due to "usrmerge"
There were patches on the mailing list couple weeks ago trying to address 
this, but some minor comments haven't been addressed yet, hence not merged:

https://lists.yoctoproject.org/g/meta-arm/topic/105575080

The original submitter hasn't responded yet and I almost forgot about it - let 
me try to re-spin the patches...
