[igt-dev] [PATCH i-g-t] tests/meson.build: fix build on cross-compiled environments

[Mauro Carvalho Chehab]

From: Mauro Carvalho Chehab <mchehab at kernel.org>

When using a cross-compilation build, test_list_target
won't be updated. So, it needs to be initialized as a blank
list, otherwise meson will abort with this error message:

	docs/reference/igt-gpu-tools/meson.build:58:1: ERROR: Unknown variable "test_list_target".

Tested using a cross-file named meson-core2.txt with:

	[properties]
	c_args = '-march=core2'

	[binaries]
	c = 'gcc'
	ar = 'ar'
	strip = 'strip'
	pkgconfig = 'pkg-config'

	[host_machine]
	system = 'linux'
	cpu_family = 'aarch64'
	cpu = 'aarch64'
	endian = 'little'

And running meson with:

	meson -Dxe_driver=enabled --cross-file meson-core2.txt core2
