I suggested to he@ that he commit this so we can quickly find which
platforms have obviously broken libm, since nobody at the time had the
resources to try every platform locally.

If you know about sparc and/or hpcsh, can you fix them by adding the
right source file in the appropriate place in the libm Makefile?

This would be needless effort.  It is a bug that the symbols are
missing.  We were shipping a busted libm.
