5884036ecd Don't use compiler flags -march=native -mtune=native in autoconf builds 
Using those flags is not acceptable for Linux distributions
because the resulting code then depends on the build
infrastructure, so the build result is not deterministic.

It is still possible to use those compiler flags by specifying
CXXFLAGS.

5da09f241c README: Remove the reference to version 3.05.02 
Versions 4.1.1 and 5.0.0 still support the legacy engine with the same functionality as 3.05.02, so there is no reason to mention 3.05.02.
