Building a uclibc based toolchain

Building a uclibc based toolchain

[stl]

Hello all,
I am trying to build my own uClibc based linux toolchain for a new architecture.

I follow the following steps:

1 - I compile binutils
2 - I copy the specific and generic linux headers (from my port of
linux) into ${HEADERS_DIR}
3 - I compile gcc only with --enable-language=c and
--with-headers=${HEADERS_DIR}
4 - I compile uClibc with the previously compiled gcc
5 - I recompile gcc with --enable-language=c,c++

All is fine for the four first steps.
But I have a question:

When uClibc building is done, where should I install the uClibc
libraries (libc.a, librt.a, etc...)
and headers?

Where gcc expects to find them?

Because, when I recompile gcc (step 5), I get GCC_NO_EXECUTABLE fatal error.
The config.log shows me that the crt1.o and some standard headers are missing..

Thanks in advance for your help.

The sequence that I follow while building an uClinux toolchain is like: 
1. Building ELF compiler (only Binutils and GCC, no libraries)
2. Building elf2flt tools (ELF)
3. Building uClinux kernel
4. Building uClibc variants
5. Building uClinux toolchain
6. Building elf2flt tools  (uClinux)

The uClibc libraries are to be installed at: 
prefix/<target>-uclinux/runtime/usr e.g. prefix/arm-uclinux/runtime/usr

One should copy both 'include' and 'lib' contents at this path.
You may need to create appropriate folders for multiple variants e.g. I copy 
non-PIC libraries at above path whereas PIC libraries in the separate 
subfolder at the same path.

Thanks and Regards,
