MIPS/LD: Continue processing with refused relocations in PIC code 

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'.

	<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'.
