	I'm not exactly sure how the eABI configuration is suppose to work
with libstdc++ build, but I think it's suppose to be a generic
configuration, allowing one to specify whichever target.  It seems to be
assuming that one will configure with eabisim or eabialtivec or eabispe or
adding one of the -m options to the build CFLAGS.

	I'm not defending the documentation and maybe some additional
dependency has arisen in libstdc++ or it was assumed that people would not
build libstdc++.  However, as soon as one of those startfile/endfile pairs
is added as the default for the powerpc-eabi configuration, one no longer
can switch configurations with -myellowknife, -mads, etc.
