system setup with egcs installed

Hi all, 
   This question is a little off topic, but I do want to be able
to use egcs and gcc at the same time. As mentioned in the FAQ, 
one can use them both by symbolic links, for example

ln -sf /usr/local/egcs/bin/gcc /usr/loca/bin/gcc
ln -sf /usr/local/gcc2/bin/gcc /usr/local/bin/gcc2

with configure option --prefix=/usr/local/egcs for egcs. However,
I used --prefix=/usr/lpp/egcs instead, but the link from 

ln -sf /usr/lpp/egcs/bin/gcc /usr/lpp/bin/gcc

doesn't work (gcc -v generates error), so I simply add 
/usr/lpp/egcs/bin into my PATH. So now the egcs gcc stuff (cpp, 
g++, c++, etc.) works fine now. 

   The problem I have now is I don't know if there is any other
system file I should change (or maybe I should add 
--execute-dir=/usr/local/bin configuring egcs?) as the 
configure stuff now working flawlessly. The following is for 
tcl8.0 (I'll attach the output) and for gtk+:

/usr/lpp/src/gimp/gtk+>./configure
loading cache ./config.cache
checking for a BSD compatible install... (cached) /bin/install -c
checking whether build environment is sane... yes
checking for working aclocal... missing
checking for working autoconf... found
checking for working automake... missing
checking for working autoheader... found
checking for working makeinfo... found
checking whether make sets ${MAKE}... (cached) yes
checking host system type... configure: error: can not guess host type; 
you must specify one            

I was just wanting to test the usability of egcs, and hope I could 
use it. As I remember seeing post saying that tcl has been 
compiled using egcs. I am using all existing libraries except
new libstdc++ and libg++2.8.0b6.3 as well as stuff in the 
new gcc-lib libraries. 

The good news is that the Omni-Broker configures alright and the 
library has been compiled but later ran into compile error. 
(which is much better as it ran into g++ internal error from 
the very first function using gcc2.7.2.3 and libg++2.7.2.8).

Thanks in advance for your time.

Exactly what error did it generate?  I'm not aware of any reason why
this wouldn't work.
