Description: removed the temporary patch of
RUNSERIAL=${RUNSERIAL="env LDR_CNTRL=MAXDATA=0x20000000@DSA"}
and similaryly for RUNPARALLEL since the h5repack test failure
was fixed and this patch is no longer needed. (IBM also advices
not to hardset MAXDATA if possible.)
Tested: NASA G-ADA AIX machine, both 32 and 64 bits modes.
(No parallel test because not able to build or run MPI executables yet.)
