libtool build failure

[Andres Salomon <dilinger@queued.net>]

Hi,

The latest libtool bpo fails to build on some architectures.  The
relevant portion of the amd64 build failure:


Libtool stress test.

 73: Link option thorough search test                ok
 74: Run tests with low max_cmd_len                  FAILED (cmdline_wrap.at:43)

Mac OS X tests

 75: darwin fat compile                              skipped (darwin.at:42)

ERROR: 71 tests were run,

Please send `tests/testsuite.log' and all information you think might help:

   To: <bug-libtool@gnu.org>
   Subject: [libtool 2.2.6b] testsuite: 74 failed


You may investigate any problem if you feel able to do so, in which
case the test suite provides a good starting point.  Its output may
be found below `tests/testsuite.dir'.

make[4]: *** [check-local] Error 1


That's from
https://buildd.debian.org/fetch.cgi?pkg=libtool&arch=amd64&ver=2.2.6b-2~bpo50%2B1&stamp=1266127707&file=log&as=raw

I was unable to reproduce this locally.  Building on an amd64 machine
here, I get:


Libtool stress test.

 73: Link option thorough search test                ok
 74: Run tests with low max_cmd_len                  ok


Anyone know what's going on?
