This broke the build on the gdb-armhf-ubuntu20_04 builder ( see 
https://builder.sourceware.org/buildbot/#/builders/170/builds/246 ):
...
../../binutils-gdb/gdb/csky-linux-tdep.c: In function ‘void 
csky_supply_fregset(const regset*, regcache*, int, const void*, size_t)’:
../../binutils-gdb/gdb/csky-linux-tdep.c:194:18: error: format ‘%ld’ 
expects argument of type ‘long int’, but argument 2 has type ‘size_t’ 
{aka ‘unsigned int’} [-Werror=format=]
   194 |       warning (_("Unknow size %ld of section .reg2, can not get 
value"
       | 
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   195 |    " of float registers."), len);
...

There are uses of %z in gdb, but very few, so I suppose the way to fix 
this is to use %s and pulongest.

Thanks,
