[PATCH] WebAssembly: Disable subdirectory configuration for unsupported LD

[PATCH] WebAssembly: Disable subdirectory configuration for unsupported LD

[Maciej W. Rozycki]

Remove an LD subdirectory configuration error:

*** ld does not support target wasm32-unknown-none
*** see ld/configure.tgt for supported targets
make[1]: *** [configure-ld] Error 1

which prevents binutils for the WebAssembly target from being built 
unless an explicit `--disable-ld' configuration option has been given. 
Users must not have to disable features selected by default to get a 
working configuration.

	/
	* configure.ac <wasm32-*-*> (noconfigdirs): Add `ld'.
	* configure: Regenerate.

Hi,

 It should be obvious.  Also this causes troubles with cross-target 
testing.  OK to apply?

Hello Maciej,
thank you for looking at this code! The change looks obviously correct to me.

 I have now committed this change to both repos.
