Open POSIX Testsuite: fix recipe.

There are several problems with this, still:
* We have an updated version in Haiku sources, from which changes should
be extracted and merged here.
* The Open POSIX Testsuite project is dead, and the tests have been
merged in https://github.com/linux-test-project/ltp/.
Add recipe for LTP.

Just for reference, it is Linux specific and doesn't compile at all for
us. We may try to extract relevant tests from it and ressurect the Open
POSIX testsuite...
Add netperf.
Add recipe for berkeley yacc.
libmicro: fix build

* The 3rd test deadlocks. It's just running getenv from 2 threads.
Forgot to add patch for Paladin.

spidermonkey: added recipe for version 1.8.5
