it
elfstrmerge.o compiled with clang

gold and clang seem to emit .eh_frame sections of type SHT_X86_64_UNWIND.

If they are used to compile elfutils itself, the testsuite will use one of =
the
.o files in tests/ and run elflint against it and check the output. elflint
will then complain:

elflint /home/tbaeder/elfutils/build-clang/tests/elfstrmerge.o
section [19] '.rela.eh_frame': invalid destination section type

Attached is the tests/elfstrmerge.o of an elfutils build with clang, which
exhibits this problem.
