I've managed to get lmbench to build with gcc 8.2.1 20180801 by changing the seekto() function in disk.c to use lseek64 rather than llseek.
I am not sure what the correct long term solution would be or if this is even an issue others might encounter or specific to my build environment but perhaps someone more familiar with Linux development than me can take a look a the disk.c source (specifically the seekto() function) and suggest the correct version of lseek to use.
Once lmbench builds the performance tests run ok and pass.

Default kernel regression test runs and all tests pass however the performance test does not run correctly due to compilation errors.

I am still looking into the cause of the issue to see if I can provide better feedback.

Update: Just discovered that this a known issue with the kernel-test suite and that jforbes is looking into it.
