  Log Message:
  -----------
  [AIX] In assembly file, create a dummy text renamed to an empty string (#73052)

This works around an AIX assembler and linker bug. If the
-fno-integrated-as and -frecord-command-line options are used but
there's no actual code in the source file, the assembler creates an
object file with only an .info section. The AIX linker rejects such an
object file.
