Iliyan Malchev b375e71d30 build: remove prelinker build build system 
This patch removes support for prelinking from the build system.  By now, the
prelinker has outlived its usefulness for several reasons.  Firstly, the
speedup that it afforded in the early days of Android is now nullified by the
speed of hardware, as well as by the presence of Zygote.  Secondly, the space
savings that come with prelinking (measued at 17MB on a recent honeycomb
stingray build) are no longer important either.  Thirdly, prelinking reduces
the effectiveness of Address-Space-Layout Randomization.  Finally, since it is
not part of the gcc suite, the prelinker needs to be maintained separately.

The patch deletes apriori, soslim, lsd, isprelinked, and iself from the source
tree.  It also removes the prelink map.

LOCAL_PRELINK_MODULE becomes a no-op.  Individual Android.mk will get cleaned
separately.  Support for prelinking will have to be removed from the recovery
code and from the dynamic loader as well.
