[erlang-bugs] --enable-native-libs is broken

[Louis-Philippe Gauthier]

Hi Kostis,
Doing make clean doesn't work since the Makefiles are not generated yet...

Downloads $ tar -xzf otp_src_17.1.tar.gz && cd otp_src_17.1/
otp_src_17.1 $ make clean
make: *** No rule to make target `clean'.  Stop.

I've written a new Gentoo Ebuild that installs from Git and everything
works as expected. I'll just install from Git when I need native libs.

ebuild: https://gist.github.com/lpgauth/00d16e006be059b75d26

h052 erlang # erl
Erlang/OTP 17 [erts-6.1.2] [source] [64-bit] [smp:32:32] [async-threads:10]
[hipe] [kernel-poll:false]

Eshell V6.1.2  (abort with ^G)
1> code:is_loaded(gen_server).
{file,"/usr/lib64/erlang/lib/stdlib-2.1.1/ebin/gen_server.beam"}
2> code:is_module_native(gen_server).
true

By the way, I've tried reproducing the HiPE binary "corruption" issue I was
experiencing on R16 and it seems fixed.

Thanks,
LP
