The Modules/getbuildinfo.c allows the use of DATE and TIME macros to be defined via CFLAGS. These vars, control the build date & time when the interpreter is opened, and can be read via the `platform._sys_version()` function. So, a conversion from SOURCE_DATE_EPOCH to DATE & TIME is required at build-time. This is especially needed for `platform._sys_version()` to work. The installation of pip seems to rely on this. The logic has been adapted from: https://wiki.debian.org/ReproducibleBuilds/TimestampsProposal#Makefile Signed-off-by: Alexandru Ardelean <ardeleanalex@gmail.com>
