I get "unexpected reloc type in static binary" and a segfault:

  bash-4.0$ package/check 
  Checking commands in ./command...
  + cd compile
  + exec make check
  ./check-local chpst runit runit-init runsv runsvchdir runsvdir sv svlogd utmpset
  Checking chpst...
  Checking runit...
  unexpected reloc type in static binarySegmentation fault
  139
  runit failed.
  make: *** [check] Error 1

This is with Glibc 2.13. Somewhat older Glibc versions work 
alright, for instance 2.11.2. As a workaround (or fix), I changed 
src/conf-ld to call "gcc" and not "gcc -s".
