+    x86: Don't include <x86intrin.h>
+    
+    Use __builtin_ia32_rdtsc directly since including <x86intrin.h> makes
+    building glibc very slow.  On Intel Core i5-6260U, this patch reduces
+    x86-64 build time from 8 minutes 33 seconds to 3 minutes 48 seconds
+    with "make -j4" and GCC 8.2.1.
+    
+            * sysdeps/x86/hp-timing.h: Don't include <x86intrin.h>.
+            (HP_TIMING_NOW): Replace _rdtsc with __builtin_ia32_rdtsc.
