commit 2dfd834840a9de8ce3866af1cf8f3aff9b1a15e8

AIX: Stop exporting any _GLOBAL__ symbol.
* m4/libtool.m4 (_LT_LINKER_SHLIBS): On AIX, GNU g++ generates
_GLOBAL__* symbols as, amongst others, landing pads for C++ exceptions.
These symbols must not be exported from shared libraries, or exception
handling may break for applications with runtime linking enabled.
