Porting applications from glibc to uClibc-ng typically involves just
recompiling the source code. uClibc-ng even supports shared libraries and
-threading. It currently runs on standard Linux and MMU-less (also
-known as µClinux) systems with support for ARC, ARM, Blackfin, i386, M68K/Coldfire
-MIPS, MIPS64, NDS32, PowerPC, SH, Sparc, X86_64 and XTENSA processors.

uClibc-ng strives to be standards compliant, which means that most
-documentation written for SuSv3, or for glibc also applies to
-uClibc-ng functions. However, many GNU extensions are not supported
-because they have not been ported, or more importantly, would
-increase the size of uClibc-ng disproportional to the added
-functionality.

-# Libstrip - A utility to optimize libraries for specific executables

-#
-# This is a surprisingly simple script that gets a list of
-# unresolved symbols in a list of executables specified on the
-# command line, and then relinks the uClibc shared object file
-# with only the those symbols and their dependencies. This
-# results in a shared object that is optimized for the executables
-# listed, and thus may not work with other executables.
-#
-# Example: optimizing uClibc for BusyBox
-# Compile uClibc and BusyBox as normal. Then, in this
-# directory, run:
-# libstrip path/to/busybox
-# After the script completes, there should be a new
-# libuClibc-0.9.5.so in the current directory, which
-# is optimized for busybox.
-#
-# How it works:
-# The uClibc Makefiles create libuClibc.so by first creating
-# the ar archive libc.a with all the object files, then links
-# the final libuClibc.so by using 'ld --shared --whole-archive'.
-# We take advantage of the linker command line option --undefined,
-# which pulls in a symbol and all its dependencies, and so relink
-# the library using --undefined for each symbol in place of
-# --whole-archive. The linker script is used only to avoid
-# having very long command lines.
