[PATCH] AMDGCN: Disable subdirectory configuration for unsupported GAS and LD

[Maciej W. Rozycki]

The `amdgcn' target is not supported by GAS or LD, so disable building 
in the respective subdirectories, removing configuration errors such as:

This target is no longer supported in gas
make[1]: *** [Makefile:5473: configure-gas] Error 1

and:

*** ld does not support target amdgcn-unknown-none
*** see ld/configure.tgt for supported targets
make[1]: *** [Makefile:6968: configure-ld] Error 1

in builds where no explicit `--disable-gas' and `--disable-ld' options 
have been used with the top-level `configure' script.  Users must not 
have to disable features selected by default to get a working 
configuration.

	/
	* configure.ac <amdgcn-*-*> (noconfigdirs): Add `ld' and `gas'.
	* configure: Regenerate.

Hi,

 This is following my observation at 
<https://inbox.sourceware.org/binutils/alpine.DEB.2.21.2511111503360.25436@angie.orcam.me.uk/>, 
and I guess fallout from changes around binutils commit 978602e83f03 
("bfd: add AMDGCN architecture") having not updated the script.

 OK to apply?  Obviously correct probably.

  Maciej
