[distortos-development] distortos + GCC 7 (experimental)

[Kamil S. <dis...@di...>]

Hi!

Today I have made some commits to make distortos ready for upcoming GCC
7 (full 7.1.0 release is expected this month). If you want to try this
experimental GCC version yourself, just download the script and build
it (;

The script is able to produce a working toolchain for Linux. It is also
possible to cross-compile a toolchain for Windows (32-bit or 64-bit) -
either in Linux or in "Bash on Ubuntu on Windows" (I've heard it can be
done, but the process is painfully slow - who would expect that? (; ).
 
I've done some quick tesking of the toolchain with all chip types (in a
few optimization levels) and I believe it is working fine (;
