[RFC] Fix compilation failure of remote-fileio.c

[Eli Zaretskii <eliz@elta.co.il>]

remote-fileio.c won't compile if `struct stat' doesn't have the
`st_blocks' member.  The patch below fixes that, but I'm not sure it
(and the associated patch to gdb/configure.in, which is not shown
below) is the right fix.  Is it perhaps better not to use st_blocks at
all, and instead compute the number of blocks as shown by the patch,
for all platforms?

	* remote-fileio.c (remote_fileio_to_fio_stat)
	(remote_fileio_func_fstat) [!HAVE_STRUCT_STAT_ST_BLOCKS]:
	Support systems that don't have st_blocks in their `struct stat'.
