Daniel Stenberg ecf953432d configure: use cpp -P when needed 
Since gcc 5, the processor output can get split up on multiple lines
that made the configure script fail to figure out values from
definitions. The fix is to use cpp -P, and this fix now first checks if
cpp -P is necessary and then if cpp -P works before it uses that to
extract defined values.

Fixes #719
