mpfr: Fix obsolete ARC asm constraints

"mpfr" library build was failing due to obsolete ARC asm constraints.

This commit replaces obsolete "J" constraints with up-to-date "Cal"
ones in order to fix "mpfr" build for ARC.

+mpfr-longlong.h: Fix obsolete ARC asm constraints
+
+This patch replaces obsolete ARC "J" asm constraint with
+up-to-date "Cal" constraint.
+The patch should be applied to upstream "mpfr" library and
+after that it should be removed from buildroot as soon as 
+mpfr version with current fix will come up.
