[gentoo-dev] [PATCH distutils-r1 1/2] Explicitly set --build-lib for distutils.

[Michał Górny]

Some of the packages want to access that directory (lxml for example),
and they have to do globbing to guess the suffix. Since we use
per-implementation build dirs anyway, let's just use a simple '/lib'
there.

I'm doing this for out-of-source builds only since we don't set
--build-base for in-source anyway. With in-source builds, we allow
setup.py to control the build locations. You can treat it as a safe
switch to disable our hackery for packages which are broken by it.
