* elf32-arm.h (elf32_arm_copy_private_bfd_data): Don't refuse
	attempts to mix PIC code with non-PIC, just mark the output as
	being position dependent.
	(elf32_arm_merge_private_bfd_data): Likewise.  Print an error
	message for EF_SOFT_FLOAT mismatches.  Display diagnostics for
	all mismatches, not just the first one.
