RTIMULibDrive does not build as indicated in documentation

[swpalmer-cl]

Instructions here: https://www.raspberrypi.com/documentation/accessories/sense-hat.html#install indicate that :

• RTIMULibDrive, RTIMULibDrive10, and RTIMULibDrive11 should build with make
• RTIMULibDrive11 is pre-compiled

Both of these are wrong. Following the instuctions on that page you will find thatRTIMULibDrive11 is not pre-ciompiled and that any attempt to make any those three projects results in the following linker errors:

RTIMULibDrive.cpp:(.text+0x34): undefined reference to `RTIMUSettings::RTIMUSettings(char const*)'
/usr/bin/ld: RTIMULibDrive.cpp:(.text+0x40): undefined reference to `RTIMU::createIMU(RTIMUSettings*)'
/usr/bin/ld: RTIMULibDrive.cpp:(.text+0xe8): undefined reference to `RTMath::currentUSecsSinceEpoch()'
