Implemented the wrong prototype.

Usedful for implementing stdio.

If we already have a clean tree xargs won't find any object files.
Add the -f argument to rm so that it doesn't complain about the lack
of arguments.

If we can't find a symbol, return null.  This occurs with libjsig symbols,
which need not be loaded.

We captured the precision function (which either returns an inline precision
or from an argument, via *12$) by value, then tries to update it to set a
default precision.  But since we captured it already, the update had no effect.

Change the code to return the precision function and store it in the fragment
instead.

libstdc++ uses this semistandard function in its locale implementation.

This ensures that initialized thread local variables are loaded into the
memory image and are usable.

When loading a small library (libverify.so) this happens.  Since it's legal,
allow it.

Change the directory structure a little to conform with jvm expecations
(removing server/ from libjvm.so).

dlopen() uses files, so do so as well.  Change DT_NEEDED handling to add the
path.

Needed for exception support.
