[PATCH] libbacktrace: fix b2test_buildid test on non-english locales

[Sergei Trofimovich via Gcc-patches]

From: Sergei Trofimovich <siarh...@google.com>

On LANG=ru_RU.UTF-8 'b2test_buildid' test fails due to localized readelf
output:

$ LANG=ru_RU.UTF-8 readelf -n b2test | fgrep 4e37e8f
    ID сборки: 4e37e8fead8d6e8b0a9dc95ea25cd784dff3a393
$ LANG=C readelf -n b2test | fgrep 4e37e8f
    Build ID: 4e37e8fead8d6e8b0a9dc95ea25cd784dff3a393

libbacktrace/

        * install-debuginfo-for-buildid.sh.in: Force non-localized readelf
        output with LANG=C.
