481 is an index into the symbol table;

0 is its "value";

0 is its size;

type:NOTYPE means: No type was specified;

bind:GLOBAL means: Are visible to all object files being combined;
The other bind values are LOCAL and WEAK.

2 means: STV_HIDDEN from sys/elf.h
I guess that is the problem (?)  I still think it has to do with the
linker script/mapping table/whatever.

UNDEF means:     an undefined symbol.

$ nm -p ./src/ctlib/.libs/ct.o |grep strlen
0000000000 U strlen
