Switch x86_64 from nptl back to pthreads. This isn't the correct fix but uClibc apparently never tested nptl on x86-64, and one of the assembly files doesn't support PIC.

# Build a simple cross compiler for the specified target.

# This simple compiler has no thread support, no, doesn't include
# uClibc++, and is dynamically linked against the host's shared libraries.

# Its stripped down nature makes it easy to build on an arbitrary host, and
# provides just enough capability to build a root filesystem, and to be used
# as a distcc accelerator from within that system.

# Get lots of predefined environment variables and shell functions.

Cross compiler for $ARCH from

To use: Add the "bin" subdirectory to your \$PATH, and use "$ARCH-cc" as
your compiler.

The syntax used to build the Linux kernel is:



# Strip the binaries

if [ -z "$SKIP_STRIP" ]
  cd "$STAGE_DIR"
  for i in `find bin -type f` `find "$CROSS_TARGET" -type f`
    strip "$i" 2> /dev/null

# A quick hello world program to test the cross compiler out.
# Build hello.c dynamic, then static, to verify header/library paths.

echo "Sanity test: building Hello World."
