# On FreeBSD (and probably some others), clang++ does not meet an autoconf
# assumption in identifying libtool configuration regarding shared library:
# the configure script will execute "$CC -shared $CFLAGS/$CXXFLAGS -v" and
# expect the output contains -Lxxx or -Ryyy.  This is the case for g++, but
# not for clang++, and, as a result, it will cause various errors in linking
# programs or running them with a shared object (such as some of our python
# scripts).
# To work around this problem we define a temporary variable
# "CXX_LIBTOOL_LDFLAGS".  It's expected to be defined as, e.g, "-L/usr/lib"
# to temporarily fake the output so that it will be compatible with that of
# g++.
