libtool wrapper PATH

[Masao Uebayashi <uebayasi%gmail.com@localhost>]

libtool reorders PATH internally and ignores .wrapper/bin and/or
tools/bin somehow.  This patch limits the passed PATH to .wrapper/bin
and .tools/bin.  With this commands called from libtool are also
jailed.

To do this, all commands called by libtools have to be shown as either
wrapper or tools. Probably ar and ranlib are not enough, but you can
see the idea.
