Review request for mesos.
Changes
-------
Since -R is a libtool option but not a gcc option, it doesn't work for linking
the python egg. Computed a separate PYTHON_JAVA_LDFLAGS to handle that
difference.
Summary
-------
On Linux, I've needed to build with -Wl,-rpath to nicely link against -ljvm. We
should do something like this automatically.
This patch (on Linux only) uses -Wl,-ljvm instead of -ljvm to link -ljvm so
libtool doesn't add it to dependency_libs [*]. Besides hopefully being
unnecessary, it fails to link things linked against that libtool library
because libtool doesn't add the rpath for the java libraries (even if I specify
it with -R). This also requires that the flags be added on libmesos.la and uses
the assumption that libmesos.la is linked dynamically.
[*] Things added to dependency_libs are automatically linked into any
executables linking against the library; this would be fine (and would make
sense if our header files might contain inline functions that call JNI_* calls)
if the -R settings were properly passed through, but libtool does not appear to
do this.
This addresses bug MESOS-127.

> On Linux, it is usually necessary to use something like -rpath to link
> against a library like the libjvm.so that is typically off the default
> library search path. Our current build scripts don't set this; if one doesn't
> set LDFLAGS to include -Wl,-rpath or similar, this can result in errors like:
> /scratch/charles/mesos2/build-linux/src/.libs/lt-mesos-tests: error while
> loading shared libraries: libjvm.so: cannot open shared object file: No such
> file or directory
