No idea either, you would have to look into the source code that
prepares these in trigo/gen*.c

Looking into the source code the generators are called from main.c which
executes line composed as: ("cd %s; %s/%s %s", datadir, bin_path,
GENERATOR, bin_path) and the generators create files in $CWD and unless
there is a -D parameter passed to the test the datadir defaults to ".".
The runtest/math file does cd $LTPROOT/testcases/bin before it executes
the test so I guess that by default these files end up in the
/opt/ltp/testcases/bin/ directory. But all of that code is quite messy
so I may be as well wrong.
