Subject: [PATCH] configure: fix parsing issue on include_dir option
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2009355
Upstream Status: iproute2.git commit 1d819dcc
commit 1d819dcc741e25958190e31f8186c940713fa0a8
Author: Andrea Claudi <aclaudi@redhat.com>

configure: fix parsing issue on include_dir option
configure is stuck in an endless loop if '--include_dir' option is used
without a value:
$ ./configure --include_dir
./configure: line 506: shift: 2: shift count out of range
./configure: line 506: shift: 2: shift count out of range
[...]
Fix it splitting 'shift 2' into two consecutive shifts, and making the
second one conditional to the number of remaining arguments.
A check is also provided after the while loop to verify the include dir
exists; this avoid to produce an erroneous configuration.
Fixes: a9c3d70d902a ("configure: add options ability")
