This patch is needed so that patch 8/9 (Paolo's 8/8) will work. With the recent
change to how XSI override functions are replaced, you can't rely on those
functions being present in the configure script as well as in the libtool 
script.
So, since Paolo's patch causes func_stripname to be used in the configure
script (when configuring cross only), this fix takes the simplistic approach
of providing a similar, but differently named, function for func_stripname
for the use of configure itself.  The implementation is taken from the non-XSI
libtool version.
