     5         kx ====
     5         kx   Directory names in products folder shouldn't match with any toolchain name.
     5         kx   For example, if we have toolchain name 'x86_64-glibc' then directory name
     5         kx   for this toolchain should be at least 'X86_64-glibc'.
     5         kx 
     5         kx NOTE JZ47XX GLibc:
     5         kx   The -O3 optimisation for glibc made wrong executables. We have to use -O2 only.
