Sorry for the late reply, but there is another way to solve that
problem which is to compile gdb passing the -mminimal-toc option to
gcc. This should be uniformly OK independently of the linker used.
There are also these options available, but I haven't tried them.
-mfull-toc
-mno-fp-in-toc
-mno-sum-in-toc
FWIW, using the GNU linker and reverting that patch I get this
error: ../../powerpc-ibm-aix4.3.3.0/bin/ld: invalid BFD target
`bigtoc'collect2: ld returned 1 exit status
