[MLB] Tag inferrence code needs improving

[Nick Hudson]

I've been playing more with the MLB in NetBSD pkgsrc and I'm seeing a
few problems with tag inferrences. The problem as I see it boils down to
the fact that

cc = gcc = /usr/bin/cc = /usr/bin/gcc = ...
c++ = g++ = /usr/bin/c++ = /usr/bin/g++ = ...

What is the easiest way of getting libtool to infer the correct tag? The
introduction of CC_ALIASES or somesuch set at libtool configure/build
time seems sensible. Comments?
