[oe] [PATCH] Apache2: Add libselinux dependency and Disable parallel install

[rongqing.li at windriver.com]

From: Roy.Li <rongqing.li at windriver.com>

1. Add conditional dependency on libselinux to apache2.

2. Disable parallel make install
apache2 supports parallel make install, before installation,
it will firstly call build/mkdir.sh to create needed directories.
build/mkdir.sh first checks if a directory exists or not, if not,
it will create this directory, when mkdir.sh is called by many
instances parallel, it will introduce race, namely the result of
checking says one directory does not exist, but when it tries to
mkdir, this directory has been created by other instance.
