+Fixes for IBM XL and Cray CCE builds:
+
+* Correct path to the fallback configuration used to handle mangling for
+  C++/Fortran compatibility (CCE, XL)
+
+* Change logic for detecting recursive fortran flags to (a) Include XL
+(qrecur), and (b) Be explicit, since not every compiler will correctly reject
+an incorrect option (ALL)

+NOTE: This patch has been accepted upstream
