+mpfr-longlong.h: Fix obsolete ARC asm constraints
+
+This patch replaces obsolete ARC "J" asm constraint with
+up-to-date "Cal" constraint.
+
+"J" constraint only existed in pre-upstream GCC port for ARC.
+In current upstream port "Cal" constraint is used which leads
+to compile-time error.
+
+Proposed fix is known to work in Buildroot, Crosstool-NG etc.
