[PATCH] libgo: Fix non-portable sed commands

[Jonathan Wakely via Gcc-patches]

This fixes the libgo build if /usr/bin/sed is found before
/usr/xpg4/bin/sed on Solaris.

Tested sparc-sun-solaris2.11, OK for trunk?

-- >8 --

Solaris sed does not allow '^' and '$' anchors inside groups, and does
not support the '+' meta-character.

ChangeLog:

        * libgo/Makefile.am (check-tail): Fix non-portable sed command.
        * libgo/Makefile.in: Regenerate.
        * libgo/match.sh (gobuild): Fix non-portable sed command.
