Upgrade to SDCC 4.1.0

Only tested in linux on a x86_64 machine.

I've tested this patch on my machines. unfortunately, tool building fails on both my linux and my w7cygnus (both of them run latest CPCtelera development ok) As my main machine is quite old I use an 64 bit Antix Linux (a lightweight Debian), which may have some common parts missing. I get this error: make[3]: *** No rule to make target '/home/nes/Baixades/cpctelera-sdcc-4.1.0/cpctelera/tools/sdcc-4.1.0/src/support/cpp/sdcpp.opt', needed by 's-options'. Stop.

On W7_64Cygwin I think the problem is that it needs package zlib. This Cygwin is quite old (also the pc is quite old, with connection issues), and I can't connect to cygwin repository for now, so I can't test to install that package: /home/nes/cpcdev/cpctelera/tools/sdcc-4.1.0/src/support/sdbinutils/bfd/compress.c:22:18: error fatal: zlib.h: No such file or directory

For the second problem you should try to install libz-dev (if you could).

I will try to figure out your first problem.

I found the problem, I will try to fix it in the next days.

On my W7 PC i have updated Cygwin to a newer version so I can access to its packages now. After installing package zlib-devel now I get the same error as on Antix: W7cygwin_zlibdevel_tool_building.log If zlib is finally required, I would suggest to add zlib to setup initial checkings and to cygwin installation documentation
