Here is a patch from our backlog at Mentor Graphics that addresses a
libgomp issue where setting ENABLE_LTO=1 in site.exp causes the following
error with dejagnu:
ERROR: (DejaGnu) proc "libgomp_target_compile linker_plugin9263.c
linker_plugin9263.exe executable {{additional_flags=-flto
-fuse-linker-plugin}}" does not exist.
This problem usually does not occur since the default site.exp does not
contain ENABLE_LTO=1. I tested both with and without our custom site.exp.
Is it OK for trunk? If so, please check it in since I do not have commit
rights.

* testsuite/lib/libgomp.exp: Reorder lib loads into dependency order.
Do not load_gcc_lib gcc-dg.exp and add a comment as to why.
* testsuite/libgomp.c/c.exp: load_gcc_lib gcc-dg.exp.
* testsuite/libgomp.fortran/fortran.exp: Likewise.
* testsuite/libgomp.graphite/graphite.exp: Likewise.
* testsuite/libgomp.c++/c++.exp: load_gcc_lib gcc-dg.exp.
Use dg-runtest rather than gfortran-dg-runtest.
