Remove obsolete Solaris 10 libgo support

Remove obsolete Solaris 10 libgo support

Here's the libgo part of the Solaris 10 removal patch.  I wonder if the
cleanup is worthwhile given the small size of the patch.

Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11 together with the main patch.

Thanks.  The patch to mksysinfo.sh wasn't quite right.  This was the
patch that I committed.

Hi Ian,

that was the only part I'd added at the very last minute without testing
it.  I'd already noticed the mess myself earlier this evening when it
broke my own bootstraps.  Sorry for the mess and thanks.
