Some horrid (and pretty dumb) sed & awk, something like:
for f in include/configs/*.h; do awk '/^\s*#\s*if/ {n=NR};
/^\s*#\s*endif/ && NR == n+1 {print n"d;"NR"d;"}' $f | sed -f - -i $f;
done
It was seeing yours that reminded I'd tripped over a few of them when
doing moveconfig.py manipulations and I should probably clean them up.
I did wonder if unifdef could be persuaded to do it, but I couldn't
immediately see a way of making it (without explicitly adding support
for it).
