[patch] Workaround for ar and ld for Windows cmdline length restriction

Hi I have prepared a patch that works around Windows 32k command line length restriction when invoking ar and ld, this makes using ghc's split-objs possible in practice. Tue May 9 04:15:32 FLE Daylight Time 2006 Esa Ilari Vuokko * Workaround for ar and ld for Windows cmdline length restriction There is no guarantee that algorithm works, ideally I should cut the lines at 32k, but instead I just call ar/ld for each one hundred files. Ld's case is a bit more complicated, with temp files. Algorithms aren't perfect, but I think they fit practically all packages out there (who has path to object file longer than 320+ characters, and hundred more?) Better solution would be to use ar's and ld's @file-functionality, but this isn't available in mingw's stable (or whatever) binutils yet, and of course builds for 6.4.x series will never have them, so it'd need ar/ld version checking which isn't totally trivial to add.
