Fix sol-thread.c compilation on Solaris

Building current gdb mainline with gcc 7.1 on Solaris 11.4 fails:

/vol/src/gnu/gdb/gdb/dist/gdb/sol-thread.c: In function `void _initialize_sol_thread()':

The following patch allows compilation to succeed on i386-pc-solaris2.11
and sparc-sun-solaris2.11.

* sol-thread.c (info_solthreads): Constify args.
Cast args to void *.
