Thanks for the bug report.  The configure script says

  checking for strdup... no

This causes a replacement for strdup to be included, and it is the
compilation of that file which gives errors.

I imagine your system does have strdup() -- if you can figure out why
it is not being detected, and fix that problem, it will avoid any
attempt to compile the extra strdup.c file. (Perhaps it's a macro?)

Otherwise you'll need to edit the utils/Makefile to remove the
reference to strdup.c
