Hello,

I've applied, after fixing a few issues, see below.

The entry to the DEVELOPERS file was still missing. I know it was in
your second patch, but the addition of wampcc to DEVELOPERS should have
been with this patch.

Those dependencies come from libuv, some instead of "fork()" and
"pthread_barrier_" which are the reason for libuv to have those
dependencies, we prefer to have the reason for wampcc to have those
dependencies, i.e the fact that it selects libuv. So:

	depends on BR2_TOOLCHAIN_HAS_THREADS_NPTL # libuv

and so on.

Also, another dependency was missing: BR2_TOOLCHAIN_HAS_GCC_BUG_64735.
The C++ code uses std::shared_future, which doesn't work on gcc < 7.x
on some architectures.

As I said above, I fixed those issues and applied.
