stdbool.h

[matthew green]

stdbool.h breaks building cgen-based simulators.  see:

	include/opcode/cgen.h:  unsigned int bool;
	include/opcode/cgen.h:struct { unsigned int bool; \
	include/opcode/cgen.h:#define CGEN_ATTR_BOOLS(a) ((a)->bool)


stdbool.h also causes my solaris GCC to break in some other fashion
due to confusion between bool and _Bool.


can the inclusion of stdbool.h be removed and something local (to
bfd) done?  this header invades the user's namespace far too much.
