Given how sparse this name-space is, you'll have less than 50
different values, you might want to consider something more compact,
such as a single letter for all components, and the version number last:

X2F9 	= x64-32-freebsd-9
X4F10	= x64-64-freebsd-10
A2FB9	= arm-32-freebsd-eb_oabi-9

By the time we run out of ASCII or even Unicode characters, we have
other problems.
