    go-cross: set alignment for the .rel.plt section on 32-bit architectures

    This patch is cherry picked from golang's upstream, and this patch will
    fix the package of etcd's following build error:

    ERROR: debugedit failed with exit code 256 (cmd was 'bitbake_build/tmp/sysroots/x86_64-linux/usr/lib/rpm/bin/debugedit' -b 'bitbake_build/tmp/work/cortexa7t2hf-vfp-neon-wrs-linux-gnueabi' -d '/usr/src/debug' -i -l 'bitbake_build/tmp/work/cortexa7t2hf-vfp-neon-wrs-linux-gnueabi/etcd/git-r0/debugsources.list' 'bitbake_build/tmp/work/cortexa7t2hf-vfp-neon-wrs-linux-gnueabi/etcd/git-r0/package/usr/bin/etcd'):
