da97dfdcfa Add sigstack handling to Linux ____longjmp_chk on i386.
All other i386 ports need to provide their own versions.

b50f8e42ba Check for valid stack frame in longjmp.
If longjmp restores the stack frame to an address which is beyond
the stack frame at the time of the longjmp call it would install
an uninitialized stack frame.  If compiled with _FORTIFY_SOURCE
defined, longjmp will now bail out in this situation.
