Configure pukes with egcs

[Jason Gunthorpe <jgg@gpu.srv.ualberta.ca>]

Tom,

I just tried to get diety to use egcs, but configure dies:
   mkdir build-egcs;cd build-egcs
   export CXXFLAGS="-Wall -g"
   export CC="egcc"
   export CXX="eg++"
   ../configure --disable-nls --disable-static

ltconfig: you must specify a host type if you use `--no-verify'
Try `ltconfig --help' for more information.
configure: error: libtool configure failed                   

It seems to me that the first problem is because it is trying to get the
host name, but fails because:
   egcc --print-libgcc-file-name
     /usr/lib/gcc-lib/i486-linux/egcs-2.90.05/libgcc.a   
   gcc --print-libgcc-file-name
     /usr/lib/gcc-lib/i486-linux/2.7.2.3/libgcc.a 

The extra dash messes it up. So I added --host=i486 to the configure line
and it appears to have corrected the libtool last problem as well.

dpkg --print-gnu-build-architecture with egcs as cc gives the correct
result btw.
