Rich Felker 82fa6b43b3 fix atomicity and other issues installing dynamic linker symlink
ln -sf is non-atomic; it unlinks the destination first. instead, make
a temporary link and rename it into place.

this commit also fixes some of the dependency tracking behavior for
the link. depending on the directory it's to be installed in is not
reasonable; it causes a new link to be attempted if the library
directory has been modified, but does not attempt to make a new link
just because libc has been updated. instead, depend on the target to
be linked to. this will ensure that, if prefix has changed but
syslibdir has not, the link will be updated to point to the new
prefix.

README

musl libc - a new standard library to power a new generation of
Linux-based devices. musl is lightweight, fast, simple, free, and
strives to be correct in the sense of standards-conformance and
safety.

musl is an alternative to glibc, eglibc, uClibc, dietlibc, and klibc.
For reasons why one might prefer musl, please see the FAQ and libc
comparison chart on the project website,

    http://www.musl-libc.org/

For installation instructions, see the INSTALL file.

Please refer to the COPYRIGHT file for details on the copyright and
license status of code included in musl (standard MIT license).



Greetings!

The 0.9.x release series for musl features interface coverage for all
interfaces defined in ISO C99 and POSIX 2008 base, along with a number
of non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality. As the release series progresses, we are
gradually adding support for incomplete functionality in existing
interfaces, additional functions that are deemed to be important due
to their use in real-world software, and support for new library and
language features in C11 such as thread-local storage, which is now
supported on all targets. In addition, support for additional target
cpu architectures is being added.

The number of packages build successfully against musl - either
out-of-the-box or with minor patches to address portability errors -
has exceeded 5000 and is steadily growing. In addition to application
compatibility testing, unit testing has been conducted using three
separate test frameworks and numerous additional standalone test cases
to verify the correctness of the implementation.

Included with this package is a gcc wrapper script (musl-gcc) which
allows you to build musl-linked programs using an existing gcc 3.x or
4.x toolchain on the host. There are also now at several mini
distributions (in the form of build scripts) which provide a
self-hosting musl-based toolchain and system root. These are much
better options than the wrapper script if you wish to use dynamic
linking or build packages with many library dependencies. See the musl
website for details.

The musl project is actively seeking contributors, mostly in the areas
of porting, testing, and application compatibility improvement. For
bug reports, support requests, or to get involved in development,
please visit #musl on Freenode IRC or subscribe to the musl mailing
list by sending a blank email to musl-subscribe AT lists DOT openwall
DOT com.

Thank you for using musl.

Cheers,
