glibc, Perl for ppc440GX - compile problems

[powerpc440]

Hello,

I'm trying to compile glibc-2.4 on my system but I have the error:

....
running configure fragment for sysdeps/powerpc/powerpc32/elf
checking for powerpc32 TLS support... yes
running configure fragment for sysdeps/unix/sysv/linux/powerpc
checking whether gcc -g -O2 -mlong-double-128 uses IBM extended format... no
checking whether gcc -g -O2 supports -mabi=ibmlongdouble... no
configure: error: this configuration requires -mlong-double-128 IBM 
extended format support

compiler : GCC 4.0.0 (DENX ELDK 4.0 4.0.0-1), the CPU is PPC440GX, 
Ocotea based board with own design.
I'm thinking that, the 440GX is not gut supported from GCC 4.0.0 compiler.
Do anobody already compile glibc and Perl for this platform, or can I 
find from somewhere .RPM packages?

Regards,

Zhivko

In your subject you mention Perl - what has glibc to do with it?

Are you running the native  compiler  on  the  board,  or  the  cross
compiler? Did you apply all eventually needed patches?

Which architecture did you select? ppc_4xx- ??

We build Perl without any problems.
