Subject: libgo: don't unset in shell script
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82b709f9c4c9b21761a44a08db43524efa40dcd5;p=gcc.git

libgo: don't unset in shell script

    Reportedly ksh fails to unset a variable that was not previously set.
    Change match.sh and gotest to not unset LANG, but instead set LANG=C.
    Also don't combine exporting and setting variable in a single statement.
