libcxx: Remove -flto from LDFLAGS It seems the buildbots can't handle it. Added a cmake option to find the cxxabi files as they are part of the toolchain and not in the normal path. It doesn't seem to make a difference, just gets rid of cmake warnings. Added another small GCC warning fix. It's fairly minor. This has no change in compiled size, and most likely no change in behavior. Bumped the PKG_RELEASE anyway. Signed-off-by: Rosen Penev <rosenp@gmail.com>

libcxx: Add package Currently in OpenWrt, there are two libc++: libstdcpp and uClibc++. The former is huge and the latter supports only C++98 with some basic support for C++11. Those C++ versions seem to be specific to the compiler version libcxx supports C++11 and above while being much smaller than libstdcpp. On mt7621, these are the sizes of the ipks that I get: libstdcpp: 460786 libcxx: 182881 uClibc++:67720 libcxx is faster than uClibc++ and is under active development as part of the LLVM project while uClibc++ is effectively dead. This PR modifies uclibc++.mk to expose the make menuconfig option. Further cleanup is beyond the scope of this PR. What that means is, this is not used by default. A g++-libcxx wrapper based on the uClibc++ one was added. Works the same way. Compile tested with all packages that use uclibc++.mk in their Makefiles under mipsel_24kc. kismet fails compilation but that package needs to be cleaned up and updated. Runtime tested with gddrescue, gdisk, dcwapd, bonnie++, and aircrack-ng on a TP-Link Archer C7v2. Signed-off-by: Rosen Penev <rosenp@gmail.com>

libcxx: update to 10.0.0 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. Signed-off-by: Rosen Penev <rosenp@gmail.com>

libcxx: fix build for x86/64 When building libcxx for x86/64, the library is installed in /usr/lib64. As the install section tries to copy the library from /usr/lib, this breaks build on x86/64.
