+    Support Alpha architecture for processor_count
+    
+    Alpha machines with Linux do have /proc/cpuinfo but its format is
+    different from normal Linux machines, and most specifically the
+    processor entry is missing. Moreover, Alpha machines can be configured
+    to compartimentalize their CPUs into different machines leading to
+    further confusion when reading /proc/cpuinfo.
+    
+    Using /usr/bin/nproc seems to be the most reliable method of determining
+    the number of processors on Alpha. Since reading /proc/cpuinfo is not
+    reliable this patch places the nproc method before trying /proc/cpuinfo.
+    
+    For futher reference see our downstream bug report at
+    https://bugs.gentoo.org/show_bug.cgi?id=587986
