I do not think there is any harm in having both -I,-L and
CPATH,LIBRARY_PATH.
I have not found any problems at least.

I did not delete -I${prefix}/include and -L${prefix}/lib because something
similar caused problems with qt4-mac (see r54186), and I was afraid it
might have broken other packages which have their own build programs.

I used CPATH instead of -isystem because, as for as I know, there is no matching
-lsystem which would appends to the library search path like -isystem appends
to the include search paths.
CPATH on the other hand has an equivalent LIBRARY_PATH.
