[PATCH 0/2] ld: Output error for warnings with --fatal-warnings

[H.J. Lu]

1. Since --fatal-warnings changes warnings into errors, we should output
error, instead of warning, for linker warnings.

Add %w to vfinfo to output "warning" if --fatal-warnings isn't used or
"error" otherwise.  Replace warning with %w in linker warnings.

2. Update _bfd_error_handler to output the warning prefix, which is default
to "warning".  Add %%w to _bfd_doprnt to output "error", instead of
"warning", when --fatal-warnings is used.  Update bfd_set_error_handler
to allow linker to set the warning prefix to "error" for --fatal-warnings.
Call bfd_set_error_handler after parsing all linker command-line arguments
so that config.fatal_warnings will be set for --fatal-warnings.

H.J. Lu (2):
  ld: Output error for linker warnings with --fatal-warnings
  bfd: Output error for linker --fatal-warnings option
