[PATCH] Search for libtoolize, not libtool

Hi,

build/buildcheck.sh performs a search for a variant of libtool in order
to verify an acceptable version is available. However, the similar
code in autogen.sh looks for and uses a variant of libtoolize.

Since libtoolize is the tool actually performing useful work between the
two, and buildcheck.sh fails the build if libtool isn't found, updating
buildcheck.sh to look for libtoolize seems appropriate. This specific
build failure does occur[0] when trying to cross-build subversion with
Ubuntu's (and soon Debian's) Multi-Archified libtool packages[1].

The attached patch, proposed by Helmut Grohne[2], makes said change to
buildcheck.sh.
