Switch to m4-single (again)

[MastaG]

Now that KOS switched to m4-single by default, lets give it another go.

[DC-SWAT]

I updated KOS, now everything should be compiled.

Thanks @DC-SWAT everything builds fine now.
However I'm still hitting the issue where it completely freezes when selecting an ISO file.
See: #136

This also happens when building clean from master branch.

[DC-SWAT]

Sorry, you'll have to fix the conflict, I deleted this file. I wanted to merge :))

[MastaG]

Yes it works now!
Thanks for fixing the mutex issue.

I've rebased on current master and did a complete fresh build, so from a clean /usr/loca/dc and /opt/toolchains/dc.

One other thing I did, was updating the included environ.sh based on the current one from KOS master.
I've added your changes, but one thing I noticed they added this:

# Position-Independent Code
#
# Comment this line out to enable position-independent code. Codegen is slightly
# slower, and you lose a register, but it's required when building dynamically
# linked libraries or code whose symbols aren't resolved until runtime.
#
export KOS_CFLAGS="${KOS_CFLAGS} -fno-PIC -fno-PIE"

So this is now enabled by default and Dreamshell has been built with -fno-PIC -fno-PIE.
I didn't find any problems with the ISO Loader, but if you think it can hurt other applications or modules, then I'll comment out this line.
Just let me know :)

It's fine, thank you!
