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.

Do you have dev-libs/libowfat-0.32-r2 installed?  That has the fix.

2020-11-23T21:19:16 >>> dev-libs/libowfat-0.32-r1

so maybe a dep is needed ?

I'm not sure.  It only affects GCC 10 so it's not a hard dependency for any other compiler.  So with the dependency can be considered as wrong as without it.  If you want me to add it, I can add it.
