* sysdeps/unix/sysv/linux/x86_64/sys/procfs.h [__WORDSIZE == 32]

	(elf_fpxregset_t): New type.
	(struct elf_prpsinfo): If __WORDSIZE == 32, change pr_[ug]id type
	to unsigned short int.
	* sysdeps/unix/sysv/linux/x86_64/sys/user.h
	(struct user_fpregs_struct): Fix comment.
	* sysdeps/i386/fpu/bits/mathdef.h (float_t, double_t): If
	__FLOAT_EVAL_METHOD__ is defined and 0, typedef to float resp. double.
	* sysdeps/x86_64/fpu/bits/mathdef.h: Include bits/wordsize.h.
	(float_t, double_t): If -m32 and not -mfpmath=sse, typedef to
	long double.
	* sysdeps/x86_64/fpu/bits/fenv.h: Include bits/wordsize.h.
	(fenv_t): Remove __mxcsr field for -m32.
