Check R_386_NONE/R_X86_64_NONE in eh6.d

Browse Source 
There is no need for run-time relocation when converting pointers
in .eh_frame section to DW_EH_PE_pcrel encoding.  R_386_NONE and
R_X86_64_NONE are expected since the space for run-time relocation
has been allocated.  This is an optimization.

	PR ld/19972
	* testsuite/ld-elf/eh6.d: Pass -rW to readelf and check for
	R_386_NONE or R_X86_64_NONE.
