[patch] Crashed cross gdb/MinGW host

[Masaki Muranaka <monaka@monami-software.com>]

My sh-elf-gdb on MinGW host was crashed
when I tried to debug using the serial connection.
Here is a patch.

It's possible the another plan to remove writefds
check. There is no support yet for writefds.

    * mingw-hdep.c (gdb_select)
      Add check if writefds is not NULL.
