Hi Janneke,

Reading https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html, "-fno-builtin"

it is for controlling those--which are something else.  These builtins always 
emitted inline by the compiler and are not in any library.

In gcc what we want is in libgcc.a -- and it's controlled by -nostdlib and 
-nodefaultlibs .

I've started implementing it in mescc...
