Some digging shows that relocations are broken in the version running
via yorck:

| Dump of assembler code for function atrac3_init_static_data:
| 0x000003fffcfcf51c <+640>:   brasl   %r14,0x3ff8002310c

No library is loaded in this location.

In a working binary this jumps to sinl:

There is a libm loaded in this location:
