wxOSX Retina fixes: wxImageList::GetSize().

wxImageList returns size of its bitmap as pixel size, i.e.  twice the
displayed screen on HiDPI screens.  Unfortunately,
wxImageList::GetSize() is used heavily in (generic) GUI drawing code,
e.g.  to properly size wxListCtrl's icon columns.  As wxImageList is
used primarily by controls, it seems reasonable to adjust for scaling
here, rather than requiring all users of the class to do it.

Don't link with -lm if the check using it failed.

It is useless and can, apparently, result in problems, see #15746.
