First of all, it seems that it's not that easy. FreeBSD's make
is, if I am correct, a different one than the Linux make. It
uses - if you look into date's Makefile, an include file,
named which is located outside of the date/ directory,
this is /usr/share/mk/ or /usr/src/share/mk/
or /usr/src/tools/build/mk/ You could try to write
an own Makefile on Linux, or try to work without one...

I'm not sure, but it's possible that FreeBSD can be used to
compile date so it will run on Linux (cross-compier). Because
I never tried this, I can't tell you how to achieve this.

Furthermore, I'm not sure in how far date hooks into the FreeBSD
kernel in order to work. It's completely possible that it would
be easier to implement FreeBSD's date functionality in Linux's
date command itself ("from scratch").
