gcc: remove option on SJLJ exceptions

Browse Source 
This is a very advanced option, and it seems, according to
http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't
really interesting.

Users really interested by this can always use the
BR2_EXTRA_GCC_CONFIG_OPTIONS is they want.

For some platforms, proper stack unwinding works perfectly,
while other platforms must use setjmp/longjmp exceptions for
proper stack unwinding during exception handling. Most people
can leave this set to n.
