my understanding of that error is that linking libc.so pulled in __neg* from compiler_rt first,
then it pulled in something else from the libgcc _float.o and _double.o, which both define
multiple symbols.  it's the subsequent need to pull in _float.o and _double.o for the other symbols
that caused the conflict with negsf2.pico and negdf2.pico.

if you still want more information, could you explain what you mean by "check the spec"?
