If just a specific configuration needs a little more pure space what's
the way we prefer to handle this?

- Define SYSTEM_PURESIZE_EXTRA from the the configure.ac

- Just change SYSTEM_PURESIZE_EXTRA in puresize.h (as the doc says)

- Change it there but with an ifdef only for the specific configuration

- Something else?

Thanks
