ELF support in DJGPP

This is an experimental patch. It is designed to bring ELF as optional target (C/C++), without affecting COFF functionality (your DJGPP will still produce COFF by default).

Example:
# create COFF just as before:
gcc -o my_coff.exe my_app.c
# create ELF from the same source:
gcc -o my_elf.exe -B/dev/env/DJDIR/elf my_app.c

Features include: 
ELF executables which run in True Flat mode
compatible with Linux shared objects
dynamically loadable libc.so, libm.so, libstdc++.so
can still link against static libraries (libc.a, ...)
requires no change to C/C++ code, only minor changes to Asm code
