Hmm, unfortunately, I couldn't reproduce the ".data..LPBX1" error with
my gcc-8.1.0 + ld-2.30 distributed at https://cdn.kernel.org/pub/tools/crosstool/.
Could you also try to enable CONFIG_GCOV_PROFILE_ALL=y and build the kernel?
If it causes similar error, it should be caused by gcov support.

Thank you,
