Chun-Yi Lee 6852f6984b EmbeddedPkg/VirtualRealTimeClockLib: Support SOURCE_DATE_EPOCH ... RISC-V ovmf used VirtualRealTimeClockLib but the default epoch is a compilation time. It causes that the RISC-V ovmf binary image is NOT reproducible. This patch added the support of SOURCE_DATE_EPOCH by printenv command. If SOURCE_DATE_EPOCH be found then we use it as BUILD_EPOCH. Otherwise we run date command for setting BUILD_EPOCH. For distributions want a reproducible RISC-V ovmf image, they should export SOURCE_DATE_EPOCH environment variable before building ovmf.
