I just realized this defconfig is Cortex-M4, so the glibc part is not 
possible.
I should have said uclibc instead. I think the following change could 
work:

-BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_6_1=y
-# BR2_UCLIBC_INSTALL_UTILS is not set
+BR2_TOOLCHAIN_EXTERNAL=y
+BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARMV7M_UCLIBC_STABLE=y

Could you try if this works on the board?
