aix: collect2 text files in archive
Rust places text files in archives. AIX ld ignores such files with a
warning. The collect2 wrapper for ld had been exiting with a fatal
error if it scanned an archive that contained a non-COFF file.
This patch updates collect2.c to issue a warning and ignore the file
member, matching the behavior of AIX ld. GCC can encounter archives
created by Rust and should not issue a fatal error. This changes
fatal_error to warning, with an implicit location and no associated
optimization flag.
