[FYI] {maint} tests: avoid failure due to libtool quirks in C++ demo test

[Stefano Lattarini]

Revealed by failures on NetBSD 5.1.

* t/cxx-lt-demo.sh (configure.ac): Don't define $CC to "false", as some
configure checks generated by libtool autoconf macros can still require
a C preprocessor even for packages using only C++, and bail out if it's
not found.  The problem was no apparent on Solaris and GNU/Linux because
those systems have a '/lib/cpp' program, and configure detected and used
that as a fallback C preprocessor.
