Update build instructions for Berkeley DB

- People were having problems with the .so when installing in
  alternative locations.
  Like gitian, build a static library with -fPIC that can
  be embedded into the executables.

- Add some missing steps

- Add reminder that BerkeleyDB is only needed when wallet support is
  enabled

Berkeley DB Berkeley DB
----------- -----------
You need Berkeley DB 4.8. If you have to build it yourself: It is recommended to use Berkeley DB 4.8. If you have to build it yourself:
wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz' ```bash
echo '12edc0df75bf9abd7f82f821795bcee50f42cb2e5f76a6a281b85732798364ef db-4.8.30.NC.tar.gz' | sha256sum -c BITCOIN_ROOT=$(pwd)
# -> db-4.8.30.NC.tar.gz: OK
tar -xzvf db-4.8.30.NC.tar.gz
cd build_unix/
../dist/configure --enable-cxx
make
sudo make install
# Pick some path to install BDB to, here we create a directory within the bitcoin directory
BDB_PREFIX="${BITCOIN_ROOT}/db4"
mkdir -p $BDB_PREFIX
# Fetch the source and verify that it is not tampered with
wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz'
echo '12edc0df75bf9abd7f82f821795bcee50f42cb2e5f76a6a281b85732798364ef db-4.8.30.NC.tar.gz' | sha256sum -c
# -> db-4.8.30.NC.tar.gz: OK
tar -xzvf db-4.8.30.NC.tar.gz
# Build the library and install to our prefix
cd db-4.8.30.NC/build_unix/
# Note: Do a static build so that it can be embedded into the exectuable, instead of having to find a .so at runtime
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX
make install
# Configure Bitcoin Core to use our own-built instance of BDB
cd $BITCOIN_ROOT
./configure (other args...) LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/"
```
**Note**: You only need Berkeley DB if the wallet is enabled (see the section *Disable-Wallet mode* below).
