From: Mike Frysinger <[email protected]>
Newer autotools will use both CFLAGS and <target>_CFLAGS when compiling
the <target>. Adding the build settings to the target-specific flags no
longer works as a way to compile build-time tools.
Instead, clobber the global flags. This triggers an automake warning,
but the end result actually works (unlike the existing code).

Hi Steve,
this patch was sent by Mike in 2013 [1]. You had some objections about
warnings it causes [2]. Although I understand it, I'd like it was merged,
because it's needed (taken by distros: gentoo [3], buildroot [4]) and
IMHO it cannot be implemented other way.
Also not sure, what should be changed in automake to avoid this tweek
(I might ask upstream).
Kind regards,
Petr

Yes I do remember the conversation.... So you are saying using AM_XXXX macros
like the following patch does not take care of the problem?

Who/how is -lc getting specified? Maybe the problem is how $(LDFLAGS_FOR_BUILD) is being set?
Note... Giulio's patch is doing something similar
https://lore.kernel.org/linux-nfs/[email protected]/T/#u
Does something like that as well as setting the AM_XXX help the your cross-compile?

IMHO tools/* utility must be built with cross-compiler too, not with
/usr/bin/gcc. Buildroot provide host-nfs-utils for that, especially for
rpcgen.
Please take a look at my WIP patch for bumping nfs-utils to latest in
Buildroot:
https://github.com/giuliobenetti/buildroot/commit/12671eb21d62a5474dc476381015069382775668
and please note this line:
--with-rpcgen=$(HOST_DIR)/bin/rpcgen
that means that nfs-utils must use already host-nfs-utils/rpcgen instead
of internal one to generate rpcs. This is why tools/* is not needed as
host to build target. Indeed host-nfs-utils is built when nfs-utils is
built. At least I understand this.
Can you Petr confirm that?
Because at this point the patch you're pointing is not needed.
Best regards

Sorry, I overlooked this mail. Ack, it's correct for buildroot, as I already
wrote yesterday.
But not sure if the patch isn't needed for Gentoo packaging.
I guess if needed, it still can be rebased and applied later.
Kind regards,
Petr
