[gentoo-dev] [PATCH 2/3] java-pkg-simple.eclass: respect JAVADOC_SRC_DIRS

["Volkmar W. Pogatzki" <gentoo@pogatzki.net>]

This patch helps to avoid useless runs of ejavadoc in multi-jar
packages where java-pkg-simple_src_compile is called for each jar file.
JAVADOC_SRC_DIRS can be set in the ebuild in global scope and
"use doc && ejavadoc" be called at the end of src_compile. And it no
longer needs to build a useless "ignoreme.jar".
