lm-sensors compilation failed

When I tried to compile the openwrt for my router, I encountered this error:

arm-openwrt-linux-muslgnueabi-gcc  -o prog/sensors/sensors prog/sensors/main.ro prog/sensors/chips.ro -liconv -Llib -lsensors /home/colin/openwrt/staging_dir/toolchain-arm_cortex-a15+neon-vfpv4_gcc-11.2.0_musl_eabi/lib/gcc/arm-openwrt-linux-muslgnueabi/11.2.0/../../../../arm-openwrt-linux-muslgnueabi/bin/ld: cannot find -liconv

It seems that there's something wrong with lm-sensors. How can I fix it?

Read feeds/packages/utils/lm-sensors and prog/sensors/Module.mk, then inspect the package compile output and the missing -liconv linker dependency. Reproduce the build with the reported target; done means the lm-sensors package compiles successfully without the linker failure.
