It took some time but now I am able to run kernel fptest.c (with just enough
Cortex-M FPU arch HAL). I tweaked the test so it works with floats rather than
doubles, but also has a double in order to enforce the case from comment 30.
Here's the printout:
INFO:<Run fptest in cyg_start>
INFO:<cyg_start run done>
EXIT:<FP Test done>

I'm not a GDB expert but it is likely that I'll have to implement the target
part of support for VFP registers. I'll have a lot of questions then, but for
the time being is this: would it be possible to also provide similar workaround
(xml file) for VFP?

My answer is I don't know, but it is very likely that we'll have another
iteration(s) with GDB, at least in order to adopt VFP registers.

To sum up, I would suggest to restart testing with 4.6.3 asap. That may imply
for the time being to go with GDB as-is (or with work-around) and gain some
time for Jifl's patch + VFP support.
If we agree, I hope John can produce test release before his trip to USA.
