configure: Adjust several assembler checks to remove an unused parm.

Hi,

noticed while trying to apply a new change to gcc/configure.ac

-------

In r12-3048-ge0b6d0b39c6, the GAS version parameter was removed from
the gcc_GAS_CHECK_FEATURE macro.  It seems that overlapping comit/test
cycles resulted in several AMDGCN and one Darwin commit with the now
extra parameter still present.

This causes wrong configure code to be generated when autoreconf is
used in the gcc directory.

Fixed by removing the extraneous parm from the AMDGCN and Darwin cases.

Checked that this produces “no change” to the configure output when
“autoreconf -I -I../config -I..” is used in the gcc directory.

OK if regstraps succeed on x86_64-linux and darwin?
thanks
Iain

gcc/ChangeLog:

	* configure.ac (darwin2[[0-9]]* | darwin19*): Alter use of
	gcc_GAS_CHECK_FEATURE to remove an extraneous parameter.
	(amdgcn-* | gcn-*) Likewise.
