Merge 'rickard/make-fixes-18/OTP-15551' into 'rickard/make-fixes-19/OTP-15551'

    * rickard/make-fixes-18/OTP-15551:
        Fix install phase in build system

        - Install of (mainly) documentation caused rebuild and
          modification of the source tree even when the source
          previously had been built. Also otp_patch_apply
          modified the source tree when updating documentation.
          This messed up the installation if installation was
          performed by another user than the user that originally
          built the system which not is an uncommon scenario.

        - Some documentation was installed by copying files
          instead of installing the files which caused faulty
          access rights on files.

        - The documentation was not properly updated when
          applying a patch using otp_patch_apply.
