Add more build options

Closes Bitcoin-ABC#305 This MR provides the following options: - `CMAKE_TOOLCHAIN_PREFIX`: Allow to specify the value to use as `TOOLCHAIN_PREFIX`, this let consumers reuse the most of the platform file while building for another system (ie: using `Linux64.cmake` file to build for `x86_64-pc-linux-musl` - `ENABLE_STATIC_LIBGCC`: Allow statically linking `libgcc` (default `OFF`) - `BUILD_BITCOIN_DAEMON`: Allow controlling if `bitcoind` should be built (default `ON`) NOTE: As man pages have a hard dependency on `bitcoind`, if `BUILD_BITCOIN_DAEMON=OFF` no man pages will be generated.
