x86: Check static link of dynamic objects
On Linux/x86, when -static is passed to gcc, gcc passes it to linker before all input files suitable for creating static executable. X86 linker will report error for dynamic input objects if -static is passed at command-line before all input files without --dynamic-linker unless --no-dynamic-linker is used. bfd/ PR ld/24920 * elf-linker-x86.h (elf_linker_x86_params): Add static_before_all_inputs and has_dynamic_linker. * elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Report dynamic input objects if -static is passed at command-line before all input files without --dynamic-linker unless --no-dynamic-linker is used. ld/ PR ld/24920 * emulparams/elf32_x86_64.sh: Use static.sh. * emulparams/elf_i386.sh: Likewise. * emulparams/elf_x86_64.sh: Likewise. * emulparams/static.sh: New file. * emultempl/elf-x86.em: Include "ldlex.h". * testsuite/ld-elf/pr24920.err: New file. * testsuite/ld-elf/linux-x86.exp: Run ld/24920 tests.
