On ARM systems, (armhf-linux, aarch64-linux), the catch2 package fails to build, due to a
compilation warning treated as an error:

This is also the case for i686-linux.

I think that this tries to find non-printable characters, so those with ASCII
codes 0 < value < 32 and 128 < value < 255. But char is unsigned on ARM, so
it won't do that with the code above. Therefore, this IS an error and treating
it as a warning would be very, very, bad.

Fixed in 7f101e7ceb869882b9a959cb7801aea64c26704d
Do note that this breaks libfive, which has no dependants.
