--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Do you that you were getting undefined symbols when having -lm before any
object/source file? If so this is not a gcc bug (or a linker one). This is how
single pass linker work.  Note if libm is a shared library normally it would
force the linker to link to it except on Linux distros where --as-needed is
default.
