Only call zic if available in BUILD_ROOT

this is not the case in minimalistic crossbuild sysroots.

Changes behavior of build: zic now get called with absolute path.

Following location get checked:
/usr/sbin/zic /usr/bin/zic /bin/zic /sbin/zic

SUSE and RHEL5 is using /usr/sbin/zic
ArchLinux seemd to use /usr/bin/zic at some point
