For some reason %F wasn't supported initially. Its simple enough to
handle the case difference in infinity and NaN handling to add support
for %F.

The C standard says that %f should use '[-]inf' or '[-]infinity' (which
style is implementation defined) for infinity handling and '[-]nan' for
NaN.
We where adding a '+' and had the wrong case for 'inf' and 'nan'.
Before -> After
+INF -> inf
-INF -> -inf
NaN -> nan

For %{e,E,g,G} conversion specifiers the C standard says the exponent
contains at least two digits, and only as many digits are necessary. So
instead of 1.234000e-001 we should have 1.234000e-01.

GCC 7 and newer are smart enough to realize that in test_snprintf()
the output will not fit in 0 or 4 bytes, but that it requires 9.
So it throws a warning in compile time. But in this case we are
actually testing that snprintf's return value is what it should be
while truncating the output. So let's suppress this warning here.

Instead of completely excluding those tests, mark them as skipped and
provide an noop function that marks the test as skipped where test is
not supported.
