It seems like this could just be:

set_build_options_meson(config_parms, config_file)

That avoids using reflection to get the function and is much easer to read
in my opinion

 build_install_dpdk = getattr(self, 'build_install_dpdk_%s_meson' %
> self.get_os_type())


While changes are being made here, could you convert this to use a chain of
if statements?

 build_dpdk_apps = getattr(self, 'build_dpdk_apps_%s_meson' %
> self.get_os_type())


Same as the last one.
