[ Upstream commit 98e93245113d0f5c279ef77f4a9e7d097323ad71 ]
To fix these build errors on a debian mipsel cross build environment:
builtin-diff.c: In function 'block_cycles_diff_cmp':
builtin-diff.c:550:6: error: absolute value function 'labs' given an argument of type 's64' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
550 | l = labs(left->diff.cycles);
| ^~~~
builtin-diff.c:551:6: error: absolute value function 'labs' given an argument of type 's64' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
551 | r = labs(right->diff.cycles);
| ^~~~
