Make the assembler generate an error if there is an attempt to define a section with the same name as an already defined symbol.
PR 14891 * config/obj-elf.c (obj_elf_section): Fail if the section name is already defined as a different symbol type. * testsuite/gas/elf/pr14891.s: New test source file. * testsuite/gas/elf/pr14891.d: New test driver. * testsuite/gas/elf/pr14891.s: New test expected error output. * testsuite/gas/elf/elf.exp: Run the new test.
