[patch] libstdc++: Scope configuration for vxworks to all versions

[Olivier Hainque]

Hello,

When libstdc++ is enabled for VxWorks, the high level
libstdc++-v3 configuration bits should apply the same
to all versions of the OS; also to vxworks7r2 in particular.

This patch adjusts the triplets matching rules accordingly.

We have been using this in gcc-9 based production toolchains
for a while, I tested that we can get a functional gcc-10 based
C++ + libstdc++ toolchain for Vx7r2 with this and sanity checked
that a build with libstdc++ enabled for VxWorks 6 passes on
mainline.

Olivier

        * crossconfig.m4: Turn “vxworks" matcher into “vxworks*".
        * configure.host: Likewise.
        * configure: Regenerate.
