error: #error "TLS support is required." while building glibc-initial-2.4 on x86_64

[Christopher Lang <christopher.lang@plus.cablesurf.de>]

I tried to start a fully renewed oe build system today with bitbake 1.6 and up 
to date oe checkout. I am using minimal distro/machine files. 
While building bootstrap-image/glibc-initial-2.4 on an x86_64 (AMD X2) machine 
for TARGET_ARCH = "i586" I get the following error:

I think it is related to the configure script which cannot test TLS support on 
the x86_64 host properly:

| checking for i386 TLS support... no


The full error output is on

any hint on how to resolve that problem is appreciated.

many thanks
