Subject: [PATCH 15/15] modpost: convert modpost to use HEAD_TEXT_SECTION macro.

Using the HEAD_TEXT_SECTION macro in modpost requires including a few
more files from the linux headers.

The entry in head_sections[] ".head.text*" should be ".head.text",
since only that section name is actually used by any architectures.  I
corrected this since preserving this over-broad pattern would have
involved some string concatination nastiness.
