    ignore lto-wrapper warnings for lto builds.
   =20
      I see these warnings from time to time, when configuring a build with=
  --enable-pgo-build=3Dlto, I haven't yet found out why I see these sometim=
e, and  why not. E.g. https://gcc.gnu.org/PR109241. Just ignore these when =
they appear  in test cases. lto-wrapper: warning: using serial compilation =
of N LTRANS jobs
