It means that you might want to pass those flags to the compiler.
The compiler doesn't examine any environment variables, so your
"export CFLAGS" incantation isn't going to do that, depending on the
build system.
When building a compiler, there is a bootstrap step, meaning there are
multiple compilers to pass the flags to. I thought there was already
a bug report about making this easier (#637232) which unfortunately no
one seems to be working on.

That's probably because in debian/config.defines, we have
compiler: 'gcc-4.5'
So if your gcc-4.5 comes from upstream, you would need to install a
/usr/local/bin/gcc-4.5 wrapper, too.
But what does this have to do with the "<triplet>" text in libc6-dev's
NEWS.Debian.gz?
