libbb: optionally honour libc provided SIGRTMIN/SIGRTMAX in get_signum()
When an application documents that it responds such and such to SIGRTMIN+n, that almost always means with respect to the libc-provided SIGRTMIN. Hence I disagree with the "more correct" in commit 7b276fc17594. In any case, this is rather unfortunate: 36 34 (the first shell is bash). We probably can't change default behaviour after 7 years, but at least we can provide a config option. We avoid a little code generation (repeated calls to __libc_current_sigrtmin) by stashing SIGRTMIN/SIGRTMAX in local variables, but it does cost ~50 bytes. The next patch serves as penance for that.
