Bug#778115: sflphone: ftbfs with GCC-5

thanks

ISO C99 introduced a new "isblank" function into the standard ctypes.h
header file. This patch conditionally defines "isblank" only if C99 is
not in use, and fixes the original gcc5 build problem.

But now I run into a problem that looks like a missing KDE build-dep of
some sort, but I don't know enough about qt/KDE to figure out what's
missing or why this is failing:
