Merge commit '92db5083077a8b0f8e1050507671b456fd155125'

* commit '92db5083077a8b0f8e1050507671b456fd155125':
  build: Generate pkg-config files from Make and not from configure
  build: Store library version numbers in .version files

Includes cherry-picked commits 8a34f3659371680ca523aecfd9098c28f0f809eb and
ee164727dd64c199b87118917e674b17c25e0da3 to fix issues.

Changes were also made to retain support for raise_major and build_suffix.
