I'm getting an error about a missing rpc_msg.h while building
conntrack-tools. That package selects libtirpc if
!BR2_TOOLCHAIN_HAS_NATIVE_RPC. I'm having BR build the toolchain using
ct-ng; I looked at the toolchain-crosstool-ng/Config.in and it selects
BR2_TOOLCHAIN_HAS_NATIVE_RPC because the ct-ng config that ships with BR
uses glibc 2.9. My ct-ng config uses glibc 2.14, which doesn't have
native RPC support.
I started to make a patch that allows for explicitly selecting
BR2_TOOLCHAIN_HAS_NATIVE_RPC like the external-toolchain allows, but I
ran across check_glibc function and the ext-toolchain-checked stamp and
it looks like quite a lot, so I wanted to find out if you actually want
all that for this fix.

Correct.

Seems like the good solution yes.

What problems did you encounter exactly? It should be fairly similar to
what we do for external toolchains I believe, no?
Thanks,

No problems, it just that when I started down the path, I thought it
would be just an option, but there turned out to be this whole
toolchain-checked thing behind it, so I wanted to make sure that is
what's wanted before I do it.

Yann will confirm or infirm, but since the glibc version selection is
not done in Buildroot, but directly inside Crosstool-NG, there is no
way for Buildroot to automatically now if the glibc of the toolchain
will have RPC support or not. Therefore, the only practical solution is
to have an option similar to the one we have in external toolchain,
where we leave it to the user to say whether the toolchain generated by
Crosstool-NG will have RPC support or not.
However, I haven't thought in detail about the detailed impact on the
implementation.
Thomas

Indeed.

I can't see any other solution either.
