toolchain-buildroot: make sure glibc isn't chosen when BR2_PREFER_STATIC_LIB=y

Browse Source 
(e)glibc doesn't support a fully statically linked userspace. Even a
basic program such as Busybox fails to do authentication due to glibc
loading some libraries dynamically. Therefore, we disable the
possibility of building a glibc toolchain when
BR2_PREFER_STATIC_LIB=y.
