You are better off fixing your code.  SP must always be aligned to an 8
byte boundary minimum, 16 bytes for the New ABIs.

Changing gcc would be difficult, and it isn't even clear if such a
change can be made to work.  If it is possible, the resulting code will
likely be so bad as to be nearly useless.
