Hmm, I see this in glib sources:
~/src/glib$ find . -name properties.c
./tests/refcount/properties.c
./gobject/tests/properties.c
~/src/glib$ find . -name signals.c
./tests/gobject/signals.c
./tests/refcount/signals.c
./gobject/tests/signals.c

So there are multiple files with the same name in the testsuite.  I wonder if
one test is using the same temporary files as another?  (Note that -pipe does
not prevent use of temporary files with -flto.)

I'm suspicious of what you have in
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld.  Perhaps that doesn't work with
-flto and make -j?  Also, files with the suffix .lto.o are not created by ld
but rather by lto-wrapper, part of gcc.  So you should probably report this bug
to redhat in the first instance, and perhaps then to the gcc project.
