On 32-bit Solaris SPARC (skynet machine mark2), R segfaults during byte-
compiling package "base" when compiled with `-O3`; using `-O2` instead
apparently works.
(The setup -- when just sourcing `/usr/local/skynet_bash_profile` -- on
the Solaris machines is currently quite broken anyway. In addition, R
2.14.0 messes up `LD_LIBRARY_PATH` such that the dynamic linker picks up
an incompatible [and totally outdated] version of `libgcc_s.so.1`, so `R`
cannot be run, which of course breaks the build as well. A work-around is
to create a symbolic link to the proper version in e.g.
`$SAGE_LOCAL/lib/`.)
