PATCH: use unsigned int :1 bitfield

[Ben Elliston]

Another patch hanging around in my checkout.  It's best to qualify one
bit wide bitfields as unsigned.  I believe the C standard leaves the
exact range of values for a signed :1 field up to the
implementation--am I right?

Okay for mainline?

	* config/obj-elf.h (ELF_TARGET_SYMBOL_FIELDS): Make single bit
	field unsigned.
