linker warning when mixing cc and gcc on alphaev{56,6}-dec-osf5.0

[Andrew Hobson <ahobson at eng dot mindspring dot net>]

The system linker spits out a warning when linking a file compiled
with gcc and a file compiled with the system compiler if debugging is
enabled (via -g).

The warning is:

   gccfunc.o: Bad proc symbol (gccfunc), index (0) should be a valid
   symref or indexNil

The problem exists on alphaev6-dec-osf5.0 with Compaq cc 6.1-011 and
alphaev56-dec-osf5.0 with Compaq cc 6.3-120.
