Sigh, after more testing I found problems :(

For instance on arm-linux-gnueabihf (thus defaulting to float-abi=hard),
arm_arch_v6k_thumb fails (because it tries to use thumb-1 + hard-float
which is not supported),
while the test itself would add -mfloat-abi=softfp, thus using a
supported configuration.

Is there a way to pass an argument to an effective-target directive?
(current, if one adds an argument, it's the target selector)

Or shall I add other effective-targets, eg arm_arch_v6k_thumb_softfp_ok?
