That adds a level of complication as opposed to just building

now have to know if your cc is gcc or clang. I assume most people
are like me: don't care what cc is as long as it produces runnable
binary.
Ok, if we want the easiest possible "out of the box" experience for
newbies, then I have a better idea:
- introduce a helper script / Makefile.inc / whatever, called
rumprun-detect.sh
- This script either just uses $RUMPRUN_PLATFORM if set, setting $CC /
$HOST appropriately
- If $RUMPRUN_PLATFORM is not set, it goes hunting for
*-rumprun-netbsd*-gcc on $PATH. If it finds a *single* toolchain, it uses
that automatically.
- If it does not find a toolchain, it complains.
How does that sound?
I'm not too enamoured. It adds a bunch of magic and doesn't do anything
to serve as "training wheels" for a real case. This is probably another
case of knowing to stop before making things too simple.
I'll just document the compiler extensively in the "your first rumprun
unikernel" tutorial I plan to write now.
