Switched to upstream tarballs.
Switched to libcxxabi as using libsupc++ is quite wonky.
Fixed description.
Removed patches. The fixes are cosmetic.
Added ssp patch. This one is needed for i386 and powerpc under musl.
Compile tested every C++ package in the tree with the exception of
several boost packages. There's something broken with boost.
Ran tested with gerbera.
