I'd rather test xargs' support for the option than check the OS with uname.
Something like the following might a little bit be more appropriate :
XARGS = $(shell if xargs --no-run-if-empty true </dev/null 2>/dev/null; then echo "xargs --no-run-if-empty" ; else echo "xargs" ; fi )
Best regards,
Willy
