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.
