Do not pass the main object handle from the assembler startup stub to the common ___start routine. It's only used for a pointless magic version check. Thanks to martin@ for testing various architectures.

add a hack for GCC 5 and non-x86 platforms:
build crtbeginS.o with -O1 as GCC tries to be very smart with the __DTOR_LIST__ as it believes it knows the size of the array at compile time (which is not true until link time). on SPARC and MIPS, the result was emitting a call to 0.
technically, i believe that GCC isn't "wrong" to make this choice, as the array is declared with a well-known initialiser size in the crtbegin.c compilation unit, and we have noticed that the libgcc version of this code has some hacks added, most likely to avoid being bitten by this optimisation.
this makes sshd work for me on earm and sparc with GCC 5.
