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.
