Revert compiler generated Fused Multiply Addition optimized routines (#2327)
Fixes #2326
Partially reverts commit b84c9d0cb61f3bd561da6092e15e294ae7e410e0 to
remove the use of the gcc 6 mechanism of generated multiple versions of
functions with different optimization flags, which was found to causes
crashes when dlopen'ing PROJ on CentOS 7.8 with gcc 8.3.1
