build: Add options to override BDB cflags/libs

Browse source 
Add environment settings to specify the CFLAGS and LIBS to be used for
BerkeleyDB directly. These will completely by-pass autodetection in the
same way as other similar flags.

```
BDB_CFLAGS  C compiler flags for BerkeleyDB, bypasses autodetection
BDB_LIBS    Linker flags for BerkeleyDB, bypasses autodetection
```

Implements #3921.
