I browsed the documentation :

http://gcc.gnu.org/install/specific.html#x-ibm-aix

once again and saw there really being this note :

"Some versions of the AIX binder (linker) can fail with a relocation 
overflow severe error when the -bbigtoc option is used to link 
GCC-produced object files into an executable that overflows the TOC. A 
fix for APAR IX75823 (OVERFLOW DURING LINK WHEN USING GCC AND -BBIGTOC) 
is available from IBM Customer Support and from its 
techsupport.services.ibm.com <http://techsupport.services.ibm.com/> 
website as PTF U455193."

You should check if this is the case...
