Interestingly enough, I was not hit by GCC PR/41302 because I built
with CONFIG_ARCH_WANT_FRAME_POINTERS=y and CONFIG_FRAME_POINTER=y
to work around GCC PR/37052 already which defines not only
-fno-omit-frame-pointer but also -fno-optimize-sibling-calls ☺

Trying again now, thanks to Stephen’s commit in the Debian Kernel svn.

Works, as seen on #debian-68k on OFTC.

Is there a simple TLS test programme I can run before extracting the
eglibc sysroot and building gcc, to see whether the Linux kernel is
working as expected?

Stephen: please look at the .dsc from the above URI, I had not only
to revert the commit disabling the m68k/fp series but also to remove
one and fix two others. (Furthermore – very interesting – ulimit -n
1024 was not enough…)

Note, while the kernel is in “uploadable” quality I won’t do so, as
I disabled all flavours but atari for quicker test cycles. You can
pull it from that repo though. It’s signed by:

Next steps:
• build gcc-4.4 b-d (they tightened binutils again)
• extract sysroot
• install updated linux-headers-*.deb and friends over that
• build gcc-4.4 with TLS support, hopefully…

I don't know of any. Under the NPTL sysroot, you should see this:

$ /lib/libc.so.6
...
Available extensions:
...
	Native POSIX Threads Library by Ulrich Drepper et al

You might want to remove the linux-2.6_2.6.32-23 kernel headers already in 
the sysroot first. (They are courtesy of make headers_install and worked 
fine for my purposes but I don't know how they differ from the 
linux-headers deb.)

Or you could just use the existing headers instead of the linux-headers 
deb until you get the eglibc packages built, at which point you can ditch 
the sysroot and debootstrap.
