build script goes into loop on MacOS

[unbibium]

When I run the build.sh, the steps for build1 seem to run into an uncontrolled loop where it gives the same two prompts over and over. When I run build.sh | head -20 to see how it starts, it does stop the assembler, but gives errors about missing files.

This may actually be a kernalemu bug.

Here's the first 20 lines of output:

splatty:cbmsrc nickb$ ./build.sh | head -20

This is because the echo command does not handle the backslash sequences. I had this very same issue.
It can be fixed by adding the "-e" option to the echo commands. It is included in commit 281ea10, which is part of PR #5.
