libtool/trunk/disable-lto-link-order2.patch

   1 This patch is derived from
   2 https://src.fedoraproject.org/rpms/libtool/blob/rawhide/f/libtool-2.4.6-disable-lto-link-order2.patch
   3
   4 Enabling lto will result in failure during test phase, to be precise test 67 will cause it.
   5 Compiler flags for this test (and most likely for rest of them) are inherited from actual build phase.
   6 I'm not sure if this is expected.
   7
   8 Most distribution disables this test. We try to keep it by stripping lto flags for it.
