[PATCH] Updated NPTL toolchain patch...

[Jean-Christophe Dubois]

Hi,

Thanks a lot for the patch.

I tried the provided patch and manage to get a (NPTL enabled) cross
compiler for linux/PPC32 using an linux/i686 host. I didn't really
tested the resulting crosstool chain yet but at least everything
compiled without trouble once I fixed the crosstool.sh script (there is
a little trouble around the pthreadtypes.h file for powerpc [at least
with glibc 2.3.3/2.3.4]. patch file attached)

Now this is a huge step and I almost could now use crosstool instead of
a custom shell script I hacked together some time ago.

Unfortunately it is not yet the final solution I am really looking for
as I need my host to be a Sparc Solaris 2.8 platform (I know, what a
strange idea). But when run on Sparc Solaris (trying to generate a cross
compiler for Linux/PPC) the scripts stops short when configuring glibc
(startfiles step).

basically, on solaris/sparc host, the gcc bootstrap crosscompiler seems
unable to handle the __thread keyword and this is very needed for
NPTL/TLS.

For now I am just puzzled why the same script succeed to generate the
right crosscompiler on Linux/ix86 host but fail to do so on
Solaris/sparc platform. The crosscompiler is generated but does not
support the right feature (aka __thread keyword).

Would anybody have a clue how to unleash the __thread support for my
bootstrap compiler on solaris/sparc (or is it at all possible)? Looking
for clues on google and co has not been very helpful so far ...

Thanks

JC
