[gentoo-dev] [PATCH autotools-utils 2/4] Pass --docdir to configure, and install docs from it.

[Michał Górny]

As EAPI 2 support is intended, this requires configuring the build
system to install docs into a temporary location and moving files from
it. Due to the lack of 'dodoc -r', directories inside docdir are
supported only with EAPI 4.
