Disable automatic PLT generation. Add the following patches:
Avoid computing the PLT when building the port. It may take so
long that the port building cluster thinks this is a runaway port.
Trick dialyzer into building the PLT even after the port is installed.
Let every user have his own initial PLT in ~/.dialyzer_init_plt.
When dialyzer is invoked the PLT will be rebuilt if needed.
This commit will fix both ports/105869 and the pointyhat port checks.
