This adds support for running:
AI_PRELOAD="/path/to/libfoo.so" ./singularity
Note that setting and exporting LD_PRELOAD there doesn't work,
because then those libs are loaded for every executable that
is being run after, including the plugins.
This patch also removes the use of tcmalloc from the plugins...
Before it exported LD_PRELOAD, using tcmalloc for all the command
line tools up till and including running the singularity binary,
as well as for the plugins. Now, it only preloads the tcmalloc
libraries for singularity-do-not-run-directly.
This involves making libllcommon shared, a change
that was not finished for windows/Mac.
More changes are needed to indra/newview/viewer_manifest.py
for those two operating systems, as well as to
indra/copy_win_scripts.
I did not test this on linux 32bit, nor non-standalone
on that OS, either.
I did not check voice (which will very likely not work
anyway on 64bit). And currently the webkit plugin doesn't
work for me, but I'll fix that in a different commit.
