Great!
I have also successfully made emulator with the above instructions and
using 32 bit elf_i386.xc linker script ...
However, running ./sketch, I got
Segmentation fault (core dumped) -> I might be using older git clone with
broken code. To update my local repository, would simple git pull from
command line would work?
However, the major problem is removed now ...
