data under test, removing test failures with the M68K host.

Verify that . input is rejected by 'e' conversion (and its uppercase
counterpart). Replace 0e0 input with .0e0 rather than adding new one,
because 0 significand is already covered by 0e+0 data, so there's no
need to keep this duplication.

Reject invalid formatted scanf real input data the exponent part of
which is comprised of an exponent introducing character, optionally
followed by a sign, and with no actual digits following. Such data is a
prefix of, but not a matching input sequence and it is required by ISO C
to cause a matching failure.
Currently a matching success is instead incorrectly produced along with
the conversion result according to the input significand read and the
exponent of zero, with the significand and the exponent part wholly
consumed from input.
Correct an invalid `tstscanf.c' test accordingly that expects a matching
success for input data provided in the ISO C standard as an example for
a matching failure.
Enable input data that causes test failures without this fix in place.

Add Makefile infrastructure and `float' real input data for targets
using the IEEE 754 binary32 format.
Keep input data disabled and referring to BZ #12701 for entries that are
are currently incorrectly accepted as valid data, such as '0e', '0e+',
'0x', '0x8p', '0x0p-', etc.
