Bug#1061539: wlrctl FTBFS on architectures where char is unsigned (e.g. arm*)

[Helmut Grohne]

Control: retitle -1 wlrctl FTBFS on architectures where char is unsigned
Control: tags -1 ftbfs
Control: severity -1 important

wlrctl fails to build from source on architectures where char is
unsigned as it attempts a "somechar < 0" comparison. This affects all
arm architectures. Since wlrctl never built there, such a bug should be
important. Adding debian-arm@ to Cc hoping that someone wants to handle
this.

Wow. Most of the 'unsigned char' bugs got fixed from 1998-2005, and
people learned since then that the whole world is not x86. I'm impressed
to see such a bug still existing in the wild.
