build: turn on thin static archives

Thin archives were disabled in 2012 as a workaround (IIRC) for obsolete
tooling on one of Joyent's platforms.  The last binutils versions that
didn't support them was released in 2007 so I think it's safe to assume
we can drop support for that now - except on SmartOS, where the tooling
still has a distinctive vintage feel to it.

Thin archives save space - it shrinks the size of PRODUCT_DIR by 30% -
and speed up the final linking step because it doesn't have to assemble
50 MB of static archives (twice! - first to create the archive, then to
copy it to PRODUCT_DIR).  The archives are just 3.5 MB now and no longer
copied around.
