Bug #8074: Call init_mkmf for main

• Status: Closed
• Assignee: nobu (Nobuyoshi Nakada)
• Target version: 2.1.0
• ruby -v: 2.0.0

When (({MakeMakefile})) is extended on itself there is a call to (({init_mkmf})).
This method mainly setups various global variables, but it also sets ((|@libdir_basename|)) to default value ((%"lib"%)).

When (({MakeMakefile})) is included in main object there is no call to (({init_mkmf})).
That's why ((|@libdir_basename|)) is not set for main object.

Therefore when we invoke mkmf methods on main object ((|@libdir_basename|)) is nil.
That leads to incorrect lib path when ((%--with-XXX-dir%)) is used.
