Subject: [PATCH 1/2] Fix symlink creation with unlucky ordering in destdir
 installs

Headers and pkgconfig files are both data files so they would be
appropriate for install-data-hook. In addition the pkgconfig file is
handled in the root Makefile.am, so it belongs there.

Potentially the install hooks could be executed first in src/Makefile.am
before the normal install is handled from the root Makefile.am.

Noticed due to:

/bin/sh: line 20: cd: /var/tmp/portage/media-sound/sox-14.6.0.2/image/usr/lib64/pkgconfig: No such file or directo

Leading to the installation of: /usr/lib64/sox.pc -> sox_ng.pc

Otherwise the symlinks will be created unconditionally even static
libraries were disabled with --disable-static.
