[PATCH] Add support for s390x-ibm-tpf

[Ulrich Weigand]

Hello,

this patch adds libtool support for the s390x-ibm-tpf target.
TPF is an operating system for IBM zSeries machines; GCC
supports TPF as cross-target.

This patch was provided by Jim Tison <address@hidden>.
The TPF team tested the patch:
>Tested this libtool patch: installed autoconf-2.58 and automake-1.8, ran
>bootstrap, automake, make check ... all 106 of the testcases passed (2
>were skipped); didn't write any new testcases. But many of the generated
>configure scripts did have certain of the new tpf* test constructs in
>them.

OK?

Bye,
Ulrich

        s390x-ibm-tpf host.
        * m4/libtool.m4 (_LT_CHECK_MAGIC_METHOD()): Skip all dependency
        checks for s390x-ibm-tpf hosts.
