  signal: work around Haiku issue with SIGBUS
  
  * lib/siglist.h: Add comment.
  * lib/sig2str.c (numname_table): Swap SIGBUS order, to match
  strsignal's favoring of SIGSEGV.
  * tests/test-signal.c (main): Avoid test failure.
  * doc/posix-headers/signal.texi (signal.h): Document the issue.
  Reported by Scott McCreary.
