Andy Polyakov 989f48d8c1 Avoid unnecessary pollution of object module name table. Cygwin shared
build workaround (DJGPP swallows it too). One probably should do same
as with ELF calling it COFF, but I'm very short in COFF platforms, so
I just go for easy ad-hoc solution. I'll take care of merge to 0.9.7
later.

Pick one target type from
elf - linux, FreeBSD etc
a.out - old linux
sol - x86 solaris
cpp - format so x86unix.cpp can be used
win32 - Windows 95/Windows NT
win32n - Windows 95/Windows NT NASM format

You need to define one of
ELF - elf systems - linux-elf, NetBSD and DG-UX
OUT - a.out systems - linux-a.out and FreeBSD
SOL - solaris systems, which are elf with strange comment lines
BSDI - a.out with a very primative version of as.
