Add a testfile using GCC 15 (experimental).
* libdw/dwarf.h: Add DW_LNAME_lo_user and DW_LNAME_hi_user.
* src/readelf.c (dwarf_lname_string): New function.
(dwarf_lname_name): Likewise.
(attr_callback): Handle DW_AT_language_name by calling
dwarf_lname_name.
* run-readelf-lnames.sh: New test.
* testfile-lnames.bz2: New testfile.
* tests/Makefile.am (TESTS): Add run-readelf-lnames.sh.
(EXTRA_DIST): Add run-readelf-lnames.sh and
testfile-lnames.bz2.
