Hello,
1.5 years ago I reported this as a bug for automake.
Stefano Lattarini just replied that it
looks like a libtool bug rather than an Automake one.
The details are here:

Hi Marcin!

I fail to reproduce. What is your $host and $build? Can you provide a
stripped down example?

Cheers,
Peter

I just realized that I didn't cross-compile. Oops. But I still cannot
reproduce (when crossing from Cygwin to MinGW), so the question still
holds: What is your $host and $build?

Cheers,

I've found the reason. In my case the problem was caused by env. variable:
GREP_OPTIONS='-I'
(libtool greps for magic string in binary file; I rarely search
strings in binaries so I have it switched off by default).

Thanks for looking into it

Marcin

Perhaps in our shell-normalization preamble in ltmain and libtoolize we
ought to `export GREP_OPTIONS=` or similar to prevent future issues?  Or
maybe that's a whole can of worms...

Thoughts?

I'd bet that clearing GREP_OPTIONS won't do any harm.
It seems to be the easiest way to fix this issue.
(just my two cents, to not let this issue be forgotten)
