This updates libtool to its current release, from 2015. Current patches
were renumbered and given a description text. The fix in
160-passthrough-ssp.patch is no longer needed.
A patch to speed up build was cherry-picked, and another openwrt
specific patch was needed to not use quotes in $(SHELL), to acommodate
our "SHELL=/usr/bin/env bash" usage.
The already present call to ./bootstrap ensures that generated files are
refreshed, so the patches are applied only to their sources. Also, that
bootstrap call was adjusted to run at the appropriate time when QUILT=1.
