There is a potentially "unsafe" use of open(). Ubuntu 8.10+, for instance,
by default enables the compiler flag -D_FORTIFY_SOURCE=2 \
which throws an error of ts_calibrate.c. To fix this, \
set a mode in the open() call, patch patched ts_calibrate.c \
to set 0644 (S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH) and it compiles fine
