PostgreSQL Version 10, missing minor version

The routine in PostGIS to parse out the version number from pg_config is
breaking in the 10 cycle.

Issue seems to be because there is no minor specified.

e.g.

pgconfig --version 

returns:

PostgreSQL 10devel

Instead of expected

PostgreSQL 10.0devel

Is this the way it's going to be or will there be a .0 tacked at the end
before release?

Thanks,
Regina
