[OE-core] [PATCH] python-native: distutils: don't use libdir, remove dead code path

[Andreas Oberritter]

* Use sys.lib instead of libdir's suffix.
* While at it, simplify redundant if/and-statments.

Coming from OE-classic it was surprising that python-native suddenly
required 'libdir' to be exported. Otherwise autoconf would fail to
detect python libraries. This happend using a customized environment
setup script to use OE's compiler and libs without bitbake.

NOTE: I'm unsure whether os.getenv("libdir").split('/')[-1] and sys.lib
actually return the same values in every case. I'm not using multilib.
Can anybody please confirm oder disprove this?

This doesn't show up as a problem when bitbake is used. I don't know
whether this would show up in an SDK setup. I'm using a script to set
up some commands to simplify working with OE's compilers and libraries,
i.e. by providing the required environment variables and parameters for
make and autotools. Having to export libdir seems odd, as it's the only
required lower case variable and is typically used by autotools in
conjunction with many other lower case variables, which already get
passed to configure as command line parameters.
