[PATCH] Skip gcore-buffer-overflow.exp on windows

[Yao Qi <yao@codesourcery.com>]

Hi,
When running gcore-buffer-overflow.exp on ia32/windows host,
we saw the following error,

  cp: accessing `XXX/gdb.base/gcore-buffer-overflow-01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789': File name too long

Looks we don't have other supported hosts that have file name length
limitation, so this patch simply skips it on windows.  Is it OK?

	* gdb.base/gcore-buffer-overflow.exp: Skip on Windows.
