'debugsec' is a 'bfd_byte *', holding the result of a
bfd_get_full_section_contents.  'info->debugsec' holds the same
contents throughout the whole xcoff read, and everywhere it's used to
read symbol names.  Simply adding a cast feels appropriate.

	* xcoffread.c (xcoff_initial_scan): Add cast to 'char *'.
