File _service:download_src_package:libtool-2.4.6-disable-lto-link-order2.patch of Package libtool

Enabling lto will result in failure during test phase, to be precise test 67 will cause it.
Compiler flags for this test (and most likely for rest of them) are inherited from actual build phase.
I'm not sure if this is expected.

Most distribution disables this test. We try to keep it by stripping lto flags for it.

Origin for this tests: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=391427
