Subject: [PATCH] configure: add the --libdir option
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2009355
Upstream Status: iproute2.git commit cee0cf84
commit cee0cf84bd32c8d9215f0c155187ad99d52a69b1
Author: Andrea Claudi <aclaudi@redhat.com>

configure: add the --libdir option
This commit allows users/packagers to choose a lib directory to store
iproute2 lib files.
At the moment iproute2 ship lib files in /usr/lib and offers no way to
modify this setting. However, according to the FHS, distros may choose
"one or more variants of the /lib directory on systems which support
more than one binary format" (e.g. /usr/lib64 on Fedora).
As Luca states in commit a3272b93725a ("configure: restore backward
compatibility"), packaging systems may assume that 'configure' is from
autotools, and try to pass it some parameters.
Allowing the '--libdir=/path/to/libdir' syntax, we can use this to our
advantage, and let the lib directory to be chosen by the distro
packaging system.
Note that LIBDIR uses "\${prefix}/lib" as default value because autoconf
allows this to be expanded to the --prefix value at configure runtime.
"\${prefix}" is replaced with the PREFIX value in check_lib_dir().
