IBM C compiler patch for GDB 6.1

[Albert Chin <gdb-patches@mlists.thewrittenword.com>]

The IBM compiler doesn't like bit types to be of type char:
  ...
  xlc -DHAVE_CONFIG_H -I. -I. -I. -D_GNU_SOURCE -DAIX_5_CORE -DAIX_CORE_DUMPX_CORE -DAIX_CORE -DAIX_WEAK_SUPPORT -I. -I. -I./../include -I./../intl -I../intl -O2 -qmaxmem=-1 -qarch=com -c bfd.c  -DPIC
  1506-507 (W) No licenses available. Contact your program supplier to add additional users. Compilation will proceed shortly.
  "elf-bfd.h", line 281.3: 1506-009 (S) Bit-field cie must be of type signed int, unsigned int or int.
  "elf-bfd.h", line 282.3: 1506-009 (S) Bit-field removed must be of type signed int, unsigned int or int.
  "elf-bfd.h", line 283.3: 1506-009 (S) Bit-field make_relative must be of type signed int, unsigned int or int.
  "elf-bfd.h", line 284.3: 1506-009 (S) Bit-field make_lsda_relative must be of type signed int, unsigned int or int.
  "elf-bfd.h", line 285.3: 1506-009 (S) Bit-field per_encoding_relative must be of type signed int, unsigned int or int.
