patch for the problem

on a fresh (january 2022) installed and fully patched Ubuntu 20.04 with fresh compiled mxe I got a lot of errors while compiling pulseview:
...
/home/sigrok/mxe-git/usr/i686-w64-mingw32.static.posix/include/boost/math/special_functions/erf.hpp:966:13: error: unable to find numeric literal operator 'operator""Q'
             BOOST_MATH_BIG_CONSTANT(T, 113, 0.11005507545746069573608988651927452e-7),
             ^
/home/sigrok/mxe-git/usr/i686-w64-mingw32.static.posix/include/boost/math/special_functions/erf.hpp:966:13: note: use -std=gnu++11 or -fext-numeric-literals to enable more built-in suffixes
...

I seems, that adding 
add_definitions(-DBOOST_MATH_DISABLE_FLOAT128=1)
to CMakeLists.txt is not enough. 
So I have to add a 
add_definitions(-fext-numeric-literals) as well:
