[coreboot] QEMU build failure in master

[Timothy Pearson]

All,

While working on the test system earlier today I noticed that QEMU 
builds are currently failing with the following error:

coreboot/src/lib/timestamp.c:184: undefined reference to 
`timer_monotonic_get'

Builds using the same configuration were working yesterday.  The 
KFSN4-DRE does not appear to be affected at this time.

Right now the test stand does not send warnings to the list about build 
failures in master.  Is this something that the community would like to 
see enabled?

Thanks!
