SDK 0.10.2 rv32m1_vega samples/subsys/logging/logger build fails

[pabigot]

This shows up in CI when modifying a file that triggers a test of this sample/platform, but is reproducible on master at a8b208a with:

cd ${ZEPHYR_BASE}/samples/subsys/logging/logger
rm -rf r5 && west build -d r5 -b rv32m1_vega_ri5cy

The result is:

[108/113] Linking C executable zephyr/zephyr_prebuilt.elf

It appears SDK 0.10.2 has a binutils patch for RISC-V to fix LUI relocation problems. I don't see any newer patches, but this one may be missing a case.

Closed with the update to SDK 0.10.3.
