Apparently not, so let me describe in more detail what I am doing and
how it fails - perhaps then someone can give me a hint about how to fix
it. To be specific, something that I don't understand is why glibc is
built multiple times and why gcc-cross depends on it. Is there a
circular dependency between gcc and glibc that OE is trying to break
this way?
Here's a summary of the problems I had:
* glibc-initial-2.3.2+cvs20040726-r22: generic bits/wordsize.h and
bits/endian.h is used instead of the x86_64 ones
* glibc-intermediate-2.5-r2: asm-x86_64 header files not found
* glibc-intermediate-2.5-r2: config-name.h not created by
configure although it is needed
* glibc-intermediate-2.5-r2: #error "__NR_pread and __NR_pread64
both defined???"
My setup:
OpenEmbedded: dev branch, pull/update today, revision e2fde1c5cf87c2b0a9be2dfac2a1a1937db68382
Bitbake: 1.6 branch, revision 638
local configs: conf/local.conf and conf/machine/x86_64.conf
x86_64.conf was derived from x86.conf with just some minor changes:
TARGET_ARCH = "x86_64", no IPKG_EXTRA_ARCHS. It is used by local.conf as
MACHINE together with DISTRO = "generic".
Bitbake tried to compile glibc-initial-2.3.2+cvs20040726-r22. The
configure task fails, with the final error being:

The configure completed, it is the GLIBC_2.3 hack with "make
sysdeps/gnu/errlist.c" which fails here. The problem comes from the fact
that -I. comes before -Isysdeps/x86_64. I have no idea where that
command line is assembled, so I went for another hack: removing the
"wrong" bits/wordsize.h and bits/endian.h.
That got me a step further to compiling glibc-intermediate-2.5-r2. Here
the problem is that it cannot find various asm-x86_64 header files like
asm-x86_64/param.h. Here's an example:

Should they also be installed in tmp/staging/x86_64-linux?
"-isystem /home/patrick/x86_64/tmp/staging/x86_64-linux/include" is part
of the link line, but the x86_64 files haven't been installed there.
linux-libc-headers_2.6.18.bb only seems to copy linux, asm and
asm-generic there. I modified its do_stage() to also install asm-x86_64,
then removed everything related to x86_64 and reran bitbake.
Hmm, installing asm-x86_64 broke glibc-intermediate's Linux kernel
header version check during the configure, so I reverted the change to
linux-libc-headers_2.6.18.bb, let bitbake configure glibc-intermediate
and manually copied asm-x86_64 before compiling it.
Next problem during compilation of glibc-intermediate: config-name.h is
not found. glibc-2.5's configure contains a comment that "For
non-generic uname, we don't need to create config-name.h at all." but
apparently it is trying to compile the generic version:
