This is an auto-filed bug because net-misc/smbc fails to compile with -fno-common or gcc-10. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info. NOTE: To reproduce this issue you may want to set CFLAGS="${CFLAGS} -fno-common" or compile it with gcc-10 that enables -fno-common by default.
