Atlas Build Failure - WORKAROUND

[Thomas D. Dean]

I attempted to install scilab on a FreeBSD -stable system with an
up-to-date ports tree.  It failed in Atlas.

I installed gcc33 and used that to build/install scilab and it worked.

Using make USE_GCC=3.3 does not pick up g77-33.  It still tries to use
/usr/bin/f77.  Temporarily linking g77-33 to /usr/bin/f77 corrected
the problem and scilab installation finished.  I restored the original
f77 after build/install completed.
