When building a program then program_CXXFLAGS replaces AM_CXXFLAGS and CXXFLAGS is appended to it, this is the reason for the double -O2 -g options when building the powertop binary. This patch removes the extra -O2 -g and returns the control of the optimization and debug flags to CXXFLAGS as one would expect. Please note that the default value of CXXFLAGS is -O2 -g if the compiler supports it.
