Specify if the compiler should default to @option{-marm} or @option{-mthumb}.
This option is only supported on ARM targets.

+Specify if the compiler should default to @option{-msse2} and

@item --with-divide=@var{type}
Specify how the compiler should generate code for checking for
division by zero. This option is only supported on the MIPS target.
