I have tested this against GCC 8 and Buildroot 2020.08.x:

BR2_TOOLCHAIN_BUILDROOT=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_TOOLCHAIN_BUILDROOT_WCHAR=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_BINUTILS_VERSION_2_32_X=y
BR2_GCC_VERSION_8_X=y
BR2_USE_MMU=y

... and all works fine. Why do you think it won't work with GCC 8?

Best,
Christian
