GCC for ELF

[OS4User]

It is impossible  to reach the desirable alignment (32 and 64)  with GCC which produces AOUT object file.  It was  clearly showed  by the recent research and Dave's build  of FFMPEG for AVX.

At same time we hope  if  GCC  _directly_ produces ELF object file it will give us a chance to get alignment 32 and 64.

Actually we need  cc1.exe, as.exe   and a kind of  elfdump.exe to get a list of exports (.def)  for wlink.
