Add a warning if an emtpty SHT_REL, SHT_RELA or SHT_PROGBITS section is detected. Disable all warnings unless the (new) lint mode is enabled.
* readelf.c (warn): New function - like elfcomm.c version but only produces output if warnings are enabled. (struct options): Add --lint and --enable-checks. (usage): Add entry for --lint. (parse_args): Handle -L. If checks are enabled but no dumps have been selected then enable all dumps. (process_section_headers): Replace long if-then-else sequence with a switch. Add warning messages for empty SHT_REL, SHT_RELA and SHT_PROGBITS sections. (process_file): Do not complain if the file is an archive and lint mode has been enabled. * elfcomm.c (error): Make the function weak. (warn): Likewise. * NEWS: Mention the new feature. * doc/binutils.texi: Document the new feature. * dwarf.h (report_leb_status): Add file name and line number parameters. Include them in the diagnostic output. (READ_ULEB): Pass file and line number to report_leb_status. (READ_SLEB): Likewise. * dwarf.c (read_and_print_leb128): Pass file and line number to report_leb_status. * testsuite/binutils-all/readelf.exp: Add test of new feature. * testsuite/binutils-all/zero-sec.s: New test source file. * testsuite/binutils-all/zero-sec.r: Expected output from new test.

+* The readelf tool now has a -L or --lint or --enable-checks option which turns
+ on warning messages about possible problems with the file(s) being examined.
+ These checks include things like zero-sized sections, which are allowed by
+ the ELF standard but which nevertheless might be of concern if the user
+ was expecting them to actually contain something.

Changes in 2.34:
* Binutils now supports debuginfod, an HTTP server for distributing
