Bug#811835: Patch for the ptlib gcc 6 FTBFS

[Adrian Bunk]

Control: reassign -1 src:ptlib
Control: forcemerge 811996 -1
Control: retitle -1 ptlib: FTBFS with GCC 6
Control: tags -1 patch

What broke the build is that gcc 6 changed the default C++ standard
from C++98 to C++14.

Not all valid C++98 code is also valid C++11 and C++14 code.

Note that this just changed the default, when told to process C++98 code 
gcc 6 does not differ in any significant way from gcc 5.

Making the code compatible with C++14 would be the best possible 
solution, but as a workaround it is possible to fix the build with
this change to tell gcc that this is C++98 code.

Adding it to STDCXXFLAGS also fixes the opal build.

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
