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. Override the lib dir suffix to fix this.

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.

Changed standard to 2a. 2a (as well as 17) contain more constexpr
functions, which are evaluated at compile time. This saves space.
Added --gc-sections. With the CXXABI change, this now makes the package
smaller.
With these, size went down to 210845 on mipsel_24kc.
Also fixed two small compiler warnings. No real change in behavior.

Allows proper exception handling. This includes removing unimplemented
warnings.
File size increased as a result:
Before:
182874
After:
211006
On mipsel_24kc.
Note that this requires libsupc++ anyway. It's specified in g++-libcxx.

Don't build with uClibc-ng. It's totally unsupported as several functions
are missing.
Make the musl libc support conditional.
Fix hash with make check FIXUP=1. Apparently I based the Makefile off of
libedit and forgot to fix the hash.

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.
