make loses LD_LIBRARY_PATH

[Adam Fedor]

I get this odd problem on my powerpc-yellowdog-linux-gnu machine with 
make 3.79.1 (see attached). For some reason, the LD_LIBRARY_PATH 
environment variable gets dropped, but most (if not all) other variables 
are still there. However, it doesn't occur on my sparc-sun-solaris2.7 
system. I've looked briefly for a cause, but I can't really see why it 
would happen.
