powerpc does not inline sqrt(3) unlike other lld archs, so it actually uses
libm and as such the `-lm' linker flag is needed.
While here, refresh WANTLIB.

GdMap is a tool which allows to visualize disk space. To display directory
structures cushion treemaps are used which visualize a complete folder or even
the whole hard drive with one picture.
Cushion treemaps display directories and files in rectangular areas. The larger
a file is the larger is the rectangle which represents it. All files in one
directory are painted within the rectangle of that directory.
