Add Math64.S to reduce the number of compiler intrinsics that need to be supported. It turns out they seem to change from GCC generation to generation.

|

# Replacement for Math64.c that is coded to use older GCC intrinsics.
|
||||
# Doing this reduces the number of intrinsics that are required when
|
||||
# you port to a new version of gcc.
|
||||
#
|
||||
# Need to split this into multple files to size optimize the image.
