I believe the change in the toolchain-external-custom is annoying

config BR2_TOOLCHAIN_EXTERNAL_INET_RPC
	bool "Toolchain has RPC support?"
	default y if BR2_TOOLCHAIN_EXTERNAL_GLIBC
	depends on !BR2_TOOLCHAIN_EXTERNAL_MUSL
	select BR2_TOOLCHAIN_HAS_NATIVE_RPC

We have to disable BR2_TOOLCHAIN_EXTERNAL_INET_RPC by default for glibc external
toolchains.

But currently most glibc toolchains in the wild still use a glibc < 2.32.

Best regards,
Romain
