Subject: Use -r (--no-run-if-empty) to xargs
X-Git-Url: https://git.distorted.org.uk/~mdw/termux-packages/commitdiff_plain/8094c664f64c030c61df33025958db9f8f3ccf89?hp=768ce14ecc1048cdfc8fcf0d51baaba5c33a163b

Use -r (--no-run-if-empty) to xargs

This avoids false error messages when building packages without
ELF files.

Fixes #373.
