>From the .config I see:

grep ^BR2_UCLIBC .config
BR2_UCLIBC_VERSION_0_9_32=y
BR2_UCLIBC_VERSION_STRING="0.9.32"
BR2_UCLIBC_CONFIG="toolchain/uClibc/uClibc-0.9.31.config"

So you try to build uClibc 0.9.32 with a 0.9.31 defconfig. That is not going to
work. Please change it to uClibc-0.9.32.config and try again.
