Apply the fix for gcc PR #9812, which fixes generation of XFmode (long double)

code on m68k. In pure gcc tradition, even though the issue has been
acknowledged as a bug introduced around gcc 2.5, it was considered as
`not a regression' with subtle semantics tricks, and only fixed in 3.4.x
although the fix was available for a long time.

Although this changes an MI file, this chunk actually removes a no longer
used function which was only ever used on m68k.
