There is no way around needing to be able to have access to solaris 10 
includes and libraries if you intend to build a linux to solaris 10 
cross-compiler.

They need to be copied into a sysroot (or nfs mounted into a sysroot) 
and then you build your toolchain.

You can probably get away initially with using only SUNWcsl SUNWcslr 
(Core shared libs) and SUNWhea (SunOS header files) packages installed 
into the sysroot to buiild your cross-toolchaiin.

After that you'll need to supply any additional libs includes as needed 
for whatever you are developing.

Note: CLFS is geared to cross-compiling a linux operating system from 
scratch, not generating cross-toolchains for solaris, so is probably not 
exactly what you are looking for here...
