Fixes build error:

seen with this defconfig

BR2_PACKAGE_LIBEST=y
The failing code was added upstream on Jul, 6th, 2020:
https://github.com/cisco/libest/commit/ab998c0918d1d46e1d8664a89b249cac08606e53
and included in version 3.2.0.
Buildroot commit 5bbb1834a412f2fb2d9692cdc40c99097fb8a46d bumped the
package to a tree including the aforementioned upstream commit on Jul
24th, 2022 so a backport to LTS branches should be considered.
