      Description

      When compiling Mongo core components on a Power9 with GCC 7 (Advance Toolchain 11.02)
      Got following error,

      The reason of this is that gcc used -DHAVE_X86INTRIN_H which was generated by
      ====================================================================================
      ./src/third_party/wiredtiger/SConscript

      if conf.CheckCHeader('x86intrin.h'):
      conf.env.Append(CPPDEFINES=[
      "HAVE_X86INTRIN_H"
      ])

      =====================================================================================
      I was told GCC 7 and later version will have the file, x86intrin.h, included, is there a way we could avoid it if the target platform is not x86?

      Thanks
