* rs6000-core.c (rs6000coff_core_p): Don't check the core file
size for full core dumps. Copy core file header to private data. (rs6000coff_core_file_failing_command, rs6000coff_core_file_failing_signal): New functions to extract the file name and terminating signal from the core file. * coff-rs6000.c: Use them.
