[fpc-pascal] Ansistrings under Android

[Dejan Boras]

It's a problem I can work around, but I'm not sure how this affects the functionality of ansistrings.

The shared library startup code for ARM is broken (well, from the svn it
seems that it never worked), it does not set up the environment variables
and call the pascal unit initialization routine.

This is a "known" issue in so far as there are some testsuite tests
(tw8730) that fail because of that.
