Makefile: Eliminate crash when building with native libs
When building with --enable-native-libs and allowing 'make' to use multiple threads, the compiler would crash because the erl_syntax module was missing. Here is the recipe for making it crash on my computer: git clean -dxfq MAKEFLAGS='-j10' ./otp_build setup -a --enable-native-libs What would happen is that when merl_transform was used to compile itself, it would call 'merl' which in turn would call erl_syntax and erl_syntax_lib. Since those modules were not listed as dependencies, there was no guarantee that they had actually been compiled. In fact, erl_syntax is a large module so a compilation it with +native would usually not finish before it was needed for compiling merl_transform. To ensure that the erl_syntax and erl_syntax_lib modules are available when needed, they must be explicitly listed as dependencies.
