config.sub...

[Ben Bergen]

Hi,

I am trying to cross compile a program for the IBM cell processor.  My
configure script for the PPE part of the compile calls the SPE
configure script using AC_CONFIG_SUBDIRS.  In the past this has worked
fine because I did not use libtool with either project and so
config.sub was never called.  I should clarify that I am calling both
configure scripts from configure.gnu wrappers passing --host=(ppu or
spu).  The cross compilers for the cell are ppu-gcc and spu-gcc
respectively.  Now my problem is that when configure calls config.sub
for libtool configuration, neither of these prefixes is recognized.  I
can fix this by changing config.sub to recognize these two prefixes
and everything works fine.  So... my question is: How can I add this
change to the GNU autotools project so that future version will
automatically handle ppu and spu compiles?  Also, is there someone
with expertise in this area so that the changes can be added correctly
and with some kind of oversight?

Thanks,
Ben
