Summary: tsk 3.2.2 missing libstdc++ in static build

Initial Comment:
The static build of the sleuthkit 3.2.2 is missing the C++ standard library.
Bindings that use the static library fail to find __cxa_pure_virtual

A work around is run:
LDFLAGS=-lstdc++ ./configure
LDFLAGS=-lstdc++ make

AC_CHECK_LIB(stdc++, main)

Message:
We have fixed this issue in pytsk by explicitly linking in libstdc++ as a
workaround but this should really not be needed because pytsk itself does
not require libstdc++. It would be cleaner to have tsk link it instead.

The issue surfaced when building a static version of pytsk on Ubuntu.

A straightforward autoconf/make solution would be to detect and include
the library.

An alternative solution could be to implement your own __cxa_pure_virtual
function

From:
http://stackoverflow.com/questions/920500/what-is-the-purpose-of-cxa-pure-virtual

The __cxa_pure_virtual function is an error handler that is invoked when a
pure virtual function is called.

If you are writing a C++ application that has pure virtual functions you
must supply your own __cxa_pure_virtual error handler function. For
example:

extern "C" void __cxa_pure_virtual() { while (1); }

Message:
Is there a autoconf/automake solution for this?  I haven't experienced this
problem yet when using the library.
