AVR-Ada V0.4.1 released

Changes:
The linker (avr-ld) of the binary packages now generates correct code for avr5 (16k-128K flash memory) targets when called with the --relax switch (default).

Building static libraries with avr-gnatmake no longer requires a host 'gcc' in the search path.

Limited support for new devices: atmega2560 atmega2561 (beta).

mk_ada_app.sh is now working directory independent, and part of the binary packages (i386-Linux, Windows).

The Linux/Windows binaries are based on gcc-4.1.1, avr-libc-1.4.4 and binutils-2.17.50 and where configured for Ada, C and C++.
