56b223c1c8 C-SKY: Make dynamic linker's name compitable with the older gcc.
__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.

7449320983 C-SKY:Fix dynamic linker's name when mfloat-abi=softfp.
The dynamic linker should be chosen according to float abi, the
predefined macro __CSKY_HARD_FLOAT__ stand for architecure not
abi.

5f72b00591 Add C-SKY port
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
user guide are available from: https://github.com/c-sky/csky-doc
