Add a scan script that checks for "-v" on the command-line, and prevents

the wrappers from adding extra flags to the command-line if "-v"
exists.  This makes "g++ -v" return the same error code for both the
wrapper and the real executable and fixes the problem with the
libtool-base build not correctly detecting the C++ compiler and thus
not adding the CXX configuration tag to the final libtool script.

Downgrade LIBTOOL_REQD to 1.5.10 since the newest version isn't needed
with this change.
