    lang/go122: fix build on armv7
    
    This backports a commit needed to get proper barriers during bootstrap
    when building Go with more than one job on armv7.
    
    Note that this only changes the behaviour when building the bootstrap
    toolchain.  Binaries generated using the toolchain are not affected
    and hence Go ports need not be bumped.
    
    PR:             278953
    Approved by:    portmgr (build fix blanket)
