The name loc_t is too enticing for developers to avoid, but it
unfortunately conflicts with a visible symbol in an AIX header file,
which repeatedly causes conflicts. This patch poisons the symbols in
GCC system.h to prevent developers from using it.
Bootstrapped on powerpc-ibm-aix7.1.0.0
Okay?
Thanks, David
