I was following http://www.openrisc.net/toolchain-build.html to learn how to setup cross compiler toolchain. and have gone down to rebuilding uClibc and found the library files are not installed in ${SYSROOT}/usr/lib correctly. (only 5 out of 8 files are copied anyhow) So I tried to do it over from scratch and now I'm stuck in compiling gcc for the first pass..
I previously installed gmp, mpfr and mpc. they were installed under /usr/local. (the headers are in /usr/local/include and the libraries are in /usr/local/lib) So for the gcc compile, I ran (at gcc-build directory)
../gcc-svn/configure --target=or32-linux --prefix=$PREFIX --disable-libssp --srcdir=../gcc-svn --enable-languages=c -- without-headers --enable-threads=single --disable-libgomp --disable-libmudflap --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local
and ran
make
and it gives me this error message (showing the error part) checking for suffix of object files... configure: error: in /home/ckim/openrisc/toolchain/gcc-build/or32-linux/libgcc': configure: error: cannot compute suffix of object files: cannot compile Seeconfig.log' for more details. make[1]: * [configure-target-libgcc] Error 1 make[1]: Leaving directory `/home/ckim/openrisc/toolchain/gcc-build' make: * [all] Error 2
so I looked into /home/ckim/openrisc/toolchain/or32-linux/libgcc/config.log file. The errored part shows this. (full log file is at http://pastebin.com/6HdfrqBy)

It's Cento6.4. building outside the source, have LD_LIBRARY_PATH and LIBRARY_PATH have /usr/local/lib (for gmp, mpfr and mpc). tried adding --program-prefix=or32-linux, tried after removing all the files.. Can anyone give me some light on this?
