perf: depend on native versions of bison and flex

Explicitly depend on bison-native and flex-native for deterministic builds,
as those are required for the build:

| Makefile.config:129: *** Error: flex is missing on this system, please install it.  Stop.
| Makefile.perf:205: recipe for target 'sub-make' failed
| make[1]: *** [sub-make] Error 2
| Makefile:68: recipe for target 'all' failed
| make: *** [all] Error 2

| Makefile.config:133: *** Error: bison is missing on this system, please install it.  Stop.
| Makefile.perf:205: recipe for target 'sub-make' failed
| make[1]: *** [sub-make] Error 2
| Makefile:68: recipe for target 'all' failed
| make: *** [all] Error 2

In most cases, those dependencies come indirectly via toolchain dependencies,
specifically binutils-cross, which pulls both bison-native and flex-native.
Different setups, such as with external toolchain, would expose this problem,
since correct dependency is not marked explicitly.

The change is build-tested on all qemu architectures.
