This patchset enables NPTL on all linux-user targets; this is a
change for i386, m68k, mipsn32, mipsn32el, mips64, mips64el,
or32, ppc64, ppc46abi32, sparc, sparc32plus, sparc64, unicore32
and x86_64 (but not plain ppc or plain mips).
Testing: I've tested with a chroot that or32 and sparc32plus work;
in both cases there were basic bugs in linux-user support (stat
didn't work on or32; pipe busted on sparc; see separate patches)
from which I conclude that these were simply untested targets,
so the bar for "make things at least not worse" is an extremely
low one. I cannot find any m68k binaries which don't die with
an illegal instruction very early on (probably because we emulate
coldfire and most m68k binaries assume 680x0), so I am treating
that target as basically also broken. I've also tested PPC and
PPC64 chroots, and of course the linux-user-0.3 testset from the wiki.
I tested x86-64 and i386 with a chroot on an ARM host: they
generally work though they still have missing bits (for instance
x86-64 has no implementation of setup_frame etc for signal handling!).
Changes v2->v3:
* fixed dumb typos in m68k pointed out by Laurent
* included Alex's patch for i386 TLS setting
* added a patch for x86-64 (turns out to be easy)
* new patch which fixes bugs in clone() argument order for
cris, x86-64, m68k, openrisc, unicore32 (noticed for
x86-64 since otherwise glibc asserts in fork; others fixed
based on examination of kernel source code)
* new patch adding a missing 'break' in i386's get_thread_area
(noticed in review of the m68k patch in that area)
* new patch which removes all the now-redundant configure
machinery and ifdefs
