While researching CircleCI build failures, I came across a linking error
relating to liblzma, where ld instructs to recompile with fPIC.

Unfortunately, this increases filesize. Added some configure flags to try
to mitigate is somewhat.

Removed maintainer as he is no longer active.

Added PKG_CPE_ID for proper CVE tracking.
