As per make(1):

For loops are expanded before tests, so a fragment such as:

.for TMACHINE in ${SHARED_ARCHS}
.if ${TMACHINE} = ${MACHINE}
...
.endif
.endfor

won't work, and should be rewritten the other way around.

So no .if in .for loops :(

But I found a solution. Rather complex but hopefuly working (will test
tonight):

echo | tr | sort | uniq | grep | awk

I'm pretty sure there's another (somewhat more simple) solution but if I
can get it to work as-is then we might improve it later.
