Seems to be a "gcc" related thing..
The errors are produced some gcc related definitions.

Did you installed all the required OS packages? (especially gcc and its version.)
You should review the MOS document written for Database 11gR2 and AIX -- your version to ensure.

Your 11gR2 Binaries can be corrupted as well, but this is a low possibility.
Check, ensure and then update me.

AIX 7.1 required packages:

bos.adt.base
bos.adt.lib
bos.adt.libm
bos.perf.libperfstat
bos.perf.perfstat
bos.perf.proctools
xlC.rte.11.1.0.2 or later
gpfs.base 3.3.0.11 or later (Only for RAC systems that will use GPFS cluster filesystems)


APARs for AIX 7.1:
IZ87216
IZ87564
IZ89165
IZ97035
See Note:1264074.1 and Note:1379908.1 for other AIX 7.1 patches that may be required

Refer to the 11.2 AIX Install Guide. Part Number E24332-01
