apache: new package

[Thomas:
 - Don't explicitly pass CC_FOR_BUILD and CFLAGS_FOR_BUILD, those are
   already part of the default environment passed by the
   autotools-package infrastructure.
 - Explicitly disable Lua and LuaJIT support to avoid mis-detection of
   host installation.
 - Explicitly handle the optional support of libxml2, OpenSSL and
   zlib. Especially, the absence of explicit handling for libxml2 was
   causing a build failure due to the host libxml2 being detected.
 - Remove /usr/manual and /usr/build from the target. This saves 20+
   MB of target space.]
