On AIX, a device driver or kernel extension can not use floating point. I did
not see a way via the configure options to get libstdc++ built with a
-msoft-float option. But there is an option to remove libraries from the list.
So I changed t-aix52 to create versions of libstdc++ to use soft float by
default with the thought that if anyone does not want them, they can delete
them when the configure gcc.
My suggested patch to t-aix52 is attached.
While getting this change to compile and link, I encountered which appears to
me to be more of a bug than an enhancement. ppc64-fp.c is needed will not
compile without modifications. I have attached my path to it as well.
