Switch from `_bfd_error_handler' to `info->callbacks->einfo' with error 
reporting concerning the use of position-dependent relocations such as 
R_MIPS_HI16 or R_MIPS_26 in PIC code and continue processing so that any 
subsequent link errors are also shown rather than the linker terminating 
right away.  This can reduce user frustration where correcting one error 
only reveals another one; instead all are shown together making them all
possible to investigate at once.  The use of the `%X' specifier causes 
the linker to terminate unsuccessfully at the end of processing.

Also fix the message to say `cannot' rather than `can not'.

	* elfxx-mips.c (_bfd_mips_elf_check_relocs) <R_MIPS16_26> 
	<R_MIPS_26, R_MICROMIPS_26_S1>: Use `info->callbacks->einfo' 
	rather than `_bfd_error_handler' to report refused relocations 
	in PIC code and continue processing.  Fix error message: `can 
	not' -> `cannot'.
