52a5669117 + enable weak externals for OpenBSD 
* converted the reference to _init in si_dll to be a weak external. This way we
  can support creating shared libraries that link to the C library as well as
  libraries that do not. If libc was linked, the compiler will link in
  crtbeginS.o and crtendS.o; _init is defined in crtbeginS.o and initializes the
  C library and calls all the C static constructors.

094ad635f7 - don't call monstartup, because that initializes the gprof profiler and should 
only be called for programs, compiled with -pg (which is not yet implemented
  for the OpenBSD target and which will use a different sysinit unit for such
  programs, when implemented)

34a8032e11 * link to crtbegin.o/crtend.o instead of crtbeginS.o/crtendS.o when creating 
normal OpenBSD programs (not shared libraries) that link to the C library,
  even when PIC code generation has been turned on. This is what gcc and clang
  do on this platform.

cf2aa6fdb7 * slight change to the OpenBSD startup code, to allow Low(__progname_storage)<>0 
(not that it's going to be changed that way, but it doesn't hurt for the code
  to be more robust; and it doesn't affect performance, since the compiler
  optimizes x-0 to x)
