[PATCH v3 2/2] python3: Enable lto if its in DISTRO_FEATURES

["Khem Raj" <raj.khem@gmail.com>]

python3 configure compiles on object file and then greps for strings in
it for endianness for target ,when using LTO the .o files are not nomal
ELF onjects so this test fails, since we are using --enable-lto to
enable this here we dont need to inject extra paths via bitbake anyway
therefore reset LTO variable for target

v3: Reset LTO variable and use --with-lto instead of --enable-lto
