gmp: Use __gnu_inline__ attribute in 4.2.1
gcc 5 defaults to C11 rules about "extern inline": this breaks any code that includes gmp.h header from gmp 4.2.1 with 'multiple definition' errors. disable-stdc patch is no longer required because of this.

+Subject: [PATCH] Use __gnu_inline__ attribute
+
+gcc5 uses C11 inline rules. This means the old "extern inline"
+semantics are not available without a special attribute.
+
+See: https://gcc.gnu.org/gcc-5/porting_to.html
+
+Upstream-Status: Inappropriate [Fixed in current versions]
