Bump autoconf requirement to 2.71 to allow regenerating configure on
more recent distributions. autoconf 2.71 has been in Fedora since F36
and is the current version in Debian stable (bookworm). It appears to
be current in Gentoo as well.
All sysdeps configure and preconfigure scripts have also been
regenerated; all changes are trivial transformations that do not affect
functionality.

The hard float abi and hard float are different,
Hard float abi: Use float register to pass float type arguments.
Hard float: Enable the hard float ISA feature.
So the with_fp_cond cannot represent these two features. When
-mfloat-abi=softfp, the float abi is soft and hard float is enabled.
So add 'with_hard_float_abi' in preconfigure and define 'CSKY_HARD_FLOAT_ABI'
if float abi is hard, and use 'CSKY_HARD_FLOAT_ABI' to determine
dynamic linker because it is what determines compatibility.
And with_fp_cond is still needed to tell glibc whether to enable
hard floating feature.
In addition, use AC_TRY_COMMAND to test gcc to ensure compatibility
between different versions of gcc. The original way has a problem
that __CSKY_HARD_FLOAT_FPU_SF__ means the target only has single
hard float-points ISA, so it's not defined in CPUs like ck810f.

Avoid fiddling with autoconf internals and use AC_DEFINE_UNQUOTED to
define macros in the configuration headers rather than handcoding an
equivalent shell sequence with the use of the `as_echo' undocumented
variable.
Switch to using AC_MSG_ERROR rather than `echo' and `exit' directly for
error handling. Owing to the lack of any kind of error annotation it
makes it difficult to spot the message in the flood in a parallel build
and neither it is logged in `config.log'.

__CSKY_HARD_FLOAT_ABI__ was added on gcc 11 to specify whether
-mfloat-abi=hard is set. On older gcc, the float ABI is defined
solely with __CSKY_HARD_FLOAT__. If __CSKY_HARD_FLOAT__ is set, it can
be either a hard-float ABI (gcc older than 11, or gcc11 -mfloat-abi=hard
(__CSKY_HARD_FLOAT_ABI__ is set) or -mfloat-abi=softfp
(__CSKY_HARD_FLOAT_ABI__ is not set). To be compatible with older gcc,
use __CSKY_HARD_FLOAT_FPU_SF__ identify if -mfloat-abi is supported,
because it is added to gcc at the same time as -mfloat-abi.

The dynamic linker should be chosen according to float abi, the
predefined macro __CSKY_HARD_FLOAT__ stand for architecure not
abi.

This patch add two abi combinations support for C-SKY ABIV2: soft-float
little endian, hard float little endian. C-SKY ABI manual and architecture
