gcc: remove option on SJLJ exceptions
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. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
