When retrying a clean build several libraries failed to build and I
finally tracked this down to the cross build tools not finding their
sysroot.
Also, on my main build server I have an older cmake version and one of the
tools claims to require cmake 3 but I see no actual incompatibility, so
I'm patching out that check.
Hackish? Yes. But it seems to work.
