To make batch linking work now that haskell98 is not automatically linked.

mkdepenC has gone away, and we don't care about C sources in nofib anyway

This allows you to use nofib in a tree built with validate

Run each nofib program multiple times, tunable by the $(NoFibRuns)
variable.  nofib-analyse already knows how to average the times from
multiple runs.

Suppress printing of the runstdtest command line in GHCi mode.

More fixes for the GHCi way

Fixes to get NoFibWithGHCi going again.

oops, I broke overriding of suffix rules when I moved the include of
suffix.mk into target.mk.  Hence, hack around it here by moving
nofib's suffix.mk after the include of target.mk.

wibbles to do with the FAST/NORM/SLOW modes.  We default to the normal
.stdout file if the .$(mode)stdout file doesn't exist, and similarly
for stderr.

Fix to make NoFib work with GHCi again.
