Add cross/firebird SynoCommunity#5795

Build FirebirdSQL database using native/libtommath and
native/libtomcrypt as dependencies.
Link against these native libraries during first step of cross build
process.

The build works for x64 architecture and DSM 7.1

- Use configure --with-cross-build as used by firebird build itself
