- as outlined in merge-request #21336 some clang compilers
can trigger erroneous floating point exceptions.
OpenFOAM normally traps FPE, but disable this in the etc/controlDict
for specific compilers:
change "trapFpe digit;" -> "trapFpe 0;"
Eliminate previous use of FOAM_SGIFPE env variable in favour of
using the etc/controlDict setting - cleaner and robuster.
