Try to fix the issue that doesn't permit us to merge libcxx with libcxxabi #6
Description
LLVM CMake has an option when building libc++abi to merge that together with libc++, so that then when you use the toolchain to compile something it's not necessary to specify to link against libc++abi.
The option is LIBCXX_ENABLE_STATIC_ABI_LIBRARY.
Last time I tried it failed on the python script that is in charge to merge the two archives.
I don't have with me the error though (sorry).
This is low priority and just a nice to have.
