building uClibc-NPTL toolchain for ARM

[Johannes Stezenbach <js at sig21 dot net>]

Hi,

I'm currently trying to build a "modern" ARM toolchain
based on gcc-4.4.4 and uClibc + NPTL, using today's
uClibc git version (0.9.31-339-g42fb51e).

As a reference I used the script at
http://uclibc.org/~kraj/toolchain-uclibc.sh

After some trial & error I got it to build mostly
(it broke when trying to build gdbserver), but the result
is of course totally untested.  I'm sending the changes
I made so far in the spirit of "release early" as
replies to this mail.

These are the sources I used:

I succeeded to build uClibc and the final gcc, but got these errors
when building gdbserver:

[ALL  ]    /home/js/temp/toolchain/i/arm-unknown-linux-uclibcgnueabi//sys-root/usr/lib/libdl.a(libdl.os): In function `_dl_load_elf_shared_library':

I guess this is a uClibc issue, but the build process itself seemed to have worked.
