Thanks for your review Nick!

In my last test I was able to save 55KiB out of 479KiB, so ~11%. But
please bear in mind that this was achieved testing on top of some TSS
changes we're developing - including mbedtls and ibmtpm20tss libraries
as subtrees.

Testing at v6.0.21 it is indeed irrelevant, I was able to save just
1KiB.

Thanks,
Mauro
