Remove SJLJ exceptions conditionals for ARM

Remove SJLJ exceptions conditionals for ARM

[Joseph S. Myers]

When updating pthread_once for libc changes I noticed a conditional on 
__USING_SJLJ_EXCEPTIONS__.  This is irrelevant for ARM EABI and so I've 
applied this patch to remove such stray SJLJ exceptions conditionals.
