# Configure flag notes:
# 1. The thread C++ library cannot be built, as the thread C library
# was not build in stage1-gcc.
# 2. Prevents the installation of precompiled include files, which are
# not needed at this stage.
# 3. From LFS: the header location of C++ needs to be explicitly given
# as we are running the configure script from the top-level
# directory.
