Subject: skip atk toolchain check

this patch is needed to work around the following gn error on
Linux arm/arm64:

ERROR at //build/config/linux/atk/BUILD.gn:13:1: Assertion failed.

assert(current_toolchain == default_toolchain)

^-----

See //ui/accessibility/BUILD.gn:297:20: which caused the file to be included.

      configs += [ "//build/config/linux/atk" ]

                   ^-------------------------
"//build/config/linux/atk" is only needed for accessibility unit tests
which we don't build
