nptl thread support with uClibc 0.9.32

nptl thread support with uClibc 0.9.32

Hello,

I believe that nptl thread support is now working in uClibc 0.9.32 (I 
have got an arm and x86 toolchain working)

Attached is a patch to enable the selection of nptl when uClibc version 
is 0.9.32

Yes, it is supposed to be official, now. ;-)

This should already be the case:
http://crosstool-ng.org/hg/crosstool-ng/file/652e56d6d35a/config/libc/uClibc.in
    19 config LIBC_UCLIBC_V_0_9_32
    20     bool
    21     prompt "0.9.32"
    22     select LIBC_UCLIBC_0_9_32_or_later
[--SNIP--]
    94 config LIBC_UCLIBC_0_9_32_or_later
    95     bool
    96     select LIBC_SUPPORT_NPTL
    97     select LIBC_UCLIBC_0_9_30_or_later

Note however that the current stable series 1.12 does not have this. As it
is a feature change, it was not, and will not be, back-ported.

Expect the next stable series (probably named 1.13) by the end of October.
Also, bear in mind that the last week of October is ELC-E and LinuxCon in
Prague, and that I'll be attending both, plus the developers' day on the
saturday, and travelling back on Sunday, so it may be late by a day or two...

Regards,
Yann E. MORIN.
