Note that having spaces in $Config{cc} is valid. Back when I was the
maintainer of Devel::CheckLib it came up, the example being 'ccache cc'.
You need to split on spaces and build the compiler invocation from the
resulting list, as well as $Config{ccflags} or whatever it's called.
Possibly re-ordering the flags if you want to add your own. Thank god I
don't maintain that code any more :-)
I suppose that, theoretically, you might even need to parse something
hateful with quoted whitespace in it. Yuck.
However, leading/trailing whitespace like in this test report is
probably an error. Given that Config.pm is created at perl build time,
it might be worth taking up with p5p.
