Improvement
Description:
RUNPARALLEL is setup with default value when --enable-parallel but only if
CC is not set.
Solution:
set RUNPARALLEL to default value of using poe when --enable-parallel
or when an MPI compiler (e.g. mpcc_r) is used.
Platforms tested:
Copper for both 32 and 64 bit, serial and parallel.
(32bit parallel had a hang problem in configure which is a different but
known problem.)
Note that one still need to setenv AR "ar -X64" for 64bit configure.
