[tboot-devel] PATCH: Remove references to __DATE__ to make the build reproducible

[Timo Lindfors]

Hi,

please consider the attached patch to help make tboot builds reproducible. 
Currently using -Werror -Wdate-time causes the build to fail.

The option -Wdate-time is described as:

    "Warn when macros __TIME__, __DATE__ or __TIMESTAMP__ are encountered
     as they might prevent bit-wise-identical reproducible compilations."
