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. Reviewed-on: https://go-review.googlesource.com/26999 From-SVN: r239443
2016-08-13crypto/aes, hash/crc32: ignore s390x specific files for nowIan Lance Taylor1-1/+1
These files are used to select s390x assembler support in the gc toolchain. We don't currently have that support, as it is written in the cmd/asm syntax rather than gas syntax. Mark the files to be ignored for now, falling back to the default implementations. Patch by Andreas Krebbel. Reviewed-on: https://go-review.googlesource.com/26994 From-SVN: r239442
