Note that the problem I have with libtool is not with installation,
but with "make check", i.e. on programs that are not installed.

In any case, as long as LD_LIBRARY_PATH is not completely deprecated
(meaning that the compilers should call the linker to generate a
working run path *by default*), binutils should be fixed to work
as previously and/or libtool should use --disable-new-dtags for
the programs that will not be installed (those for which -no-install
is used).

Actually, since Thomas gave the hint "-Wl,--disable-new-dtags", I've
searched for dtags in log files, and found:

binutils (2.27.51.20161116-2) unstable; urgency=medium

  * Stop building the mipsr6 mipsr6el mipsn32r6 mipsn32r6el mips64r6 mips64r6el
    variants; can't continue with this work, because package uploads with
    these architectures are still rejected.
  * Add homepage attribute to the control file: Closes: #841432.
  * ld: enable new dtags by default for linux/gnu targets. Closes: #835859.
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  * Fix PR ld/20827, using proposed patch. Closes: #844378.

So, the issue may be specific to Debian. Bug 835859 was just a
wishlist. And the change hasn't even been announced in NEWS.Debian!
