25591c322c libbb: introduce bb_signals and bb_signals_recursive, 
which sets same handler for many signals. sig_catch is nuked
(bb_signals_recursive is more descriptive name).
*: use them as appropriate.

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.
