Indeed, just tested, and the DISCARD linker script does not work for this as it gets added anyway when I add "-lgcc".
I see some suspicious extra .debug_frame section listed by objdump when -lgcc is there but this does not get into the binary as adding it into DISCARD works and the btoa string is still the same even when not seeing it in the output.
Not sure if everything from libgcc.a is harmless like this but looks like for this case it works fine indeed.
