I have resolved the problem of sed, now compilation fails at this stage:

<snip>
collect2: ld returned 12 exit status
make[3]: *** [cc1-dummy] Error 1

So my advices are to check what this exit code 12 means and what
that '-bbigtoc' means and whether it could clash with the GCC defaults for code production, the linker not
really understanding it, or something...
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...
