[gentoo-python] [PATCH] Override egg-info location in out-of-source builds.

[gentoo-python] [PATCH] Override egg-info location in out-of-source builds.

[Michał Górny]

Detect whether egg_info command is available and override the egg-info
file location to BUILD_DIR. This way, there is no risk that egg-info
files between CPython 2.7 and PyPy will collide. Even if that wouldn't
hurt anything :P.

Ok.
