hi,
Seems I hit this bug:
[Bug 6224] New: Cannot enable threads on arm7tdmi (MMU-less) arch
http://lists.uclibc.org/pipermail/uclibc-cvs/2013-May/031094.html
Now I switch to compile with
# ARCH_HAS_MMU is not set
LINUXTHREADS_OLD=y
# LINUXTHREADS_NEW is not set
# UCLIBC_HAS_THREADS_NATIVE is not set
UCLIBC_HAS_THREADS=y
But I got another compile error: (compile against current git tree)
