I am wondering if this is not a defect of the Bootlin
toolchains. Their sysroot should be "pure", i.e not be polluted by
extra libraries. I'm actually confused why we have ncurses in the
target sysroot in the first place, I see no reason for that.

So if that patch is solely to fix this issue with Bootlin toolchains,
I would rather fix the toolchains.
