[compiler-rt] Build custom libc++abi without exceptions.
Summary:
Since neither compiler-rt nor the libc++ we build use exceptions, we
don't need libc++abi to have them either.
This resolves an issue where libFuzzer's private libc++ contains
implementations for __cxa_throw and friends, causing fuzz targets built
with their own C++ library to segfault during exception unwinding.
See https://github.com/google/oss-fuzz/issues/2328.
