This is based on Ulrich Drepper's implementation in GLIBC, but hacked up to work
in uClibc. The differences from the GLIBC version are as follows:
- b64_from_24bit() has been converted into a macro
- Usage of GLIBC-isms (such as libc_freeres_ptr) have been removed
It is enabled by the UCLIBC_HAS_SHA256_CRYPT_IMPL configuration symbol. You must
have UCLIBC_HAS_CRYPT_IMPL enabled as well.

When debugging memory leaks with Valgrind, it is required that
dynamically loaded shared objects are not unloaded when a process exits,
otherwise symbols from those files aren't correctly resolved in
allocation traces. This patch adds the LDSO_NO_CLEANUP configuration
option to control this behaviour.

The dynamic linker can be run either indirectly through running some
dynamically linked program or library (in which case no command line options
to the dynamic linker can be passed and, in the ELF case, the dynamic linker
which is stored in the .interp section of the program is executed)
or directly by running:
/lib/ld-uClibc.so.* [OPTIONS] [PROGRAM [ARGUMENTS]]
Stand-alone execution is a prerequisite for adding prelink capabilities
to uClibc dynamic linker, as well useful for testing an updated version
of the dynamic linker without breaking the whole system.
Currently supported option:
--library-path PATH use given PATH instead of content of the environment
variable LD_LIBRARY_PATH
(Mandatory for prelinking)
Not supported options:
--list list all dependencies and how they are resolved
--verify verify that given object really is a dynamically linked
object we can handle
--inhibit-rpath LIST ignore RUNPATH and RPATH information in object names
in LIST
This feature can be enabled by setting LDSO_STANDALONE_SUPPORT=y

A new shared object, libubacktrace.so.0 is added to uClibc
to provide backtrace functions to support application self-debugging.
This set of functions requires to dynamically load libgcc_s.so so they
need to call dlopen/dlsym that are provided by libdl. For this reason
they cannot be included into libc.so.0 but are provided by a new library.
User application that wants to use backtrace needs to be compiled with
-fexceptions option and -rdynamic to get full symbols printed and must be
linked against libubacktrace.so

On hardened system it could be useful to disable the use
of LD_PRELOAD environment variable for preloading shared objects
before the system libraries. So this patch add a config option,
LDSO_PRELOAD_ENV_SUPPORT, to control this behaviour.
