ld script lower-case absolute and sizeof_headers

Browse source 
I think these happened by accident, so let's see what breaks if they
are removed.

	* ldlex.l: Remove lower case "absolute" and "sizeof_headers"
	in non-mri mode.
	* ld.texi: Remove sizeof_headers index.
	* testsuite/ld-mmix/mmohdr1.ld: Use SIZEOF_HEADERS.
