-Link mksnapshot with libatomic on x86

+Subject: [PATCH] link libatomic for clang conditionally
 
-Clang-12 on x86 emits atomic builtins
+Clang emits atomic builtin, explicitly link libatomic conditionally:
+- For target build, always link -latomic for clang as usual
+- For host build, if host and target have same bit width, cross compiling
+  is enabled, and host toolchain is gcc which does not link -latomic;
+  if host and target have different bit width, no cross compiling,
+  host build is the same with target build that requires to link
+  -latomic;
