ROMCC: Trigger internal compiler failure and apply the workaround

These boards first failed when attempting to change print_err() from
direct function call to console_tx_XX() to a code block in the form of

 do { if (y) console_tx_XX(x); } while(0)

Removing the label dummy_romcc_workaround_label added here will
trigger the following compiler error for the two boards:

  Internal compiler error: no edge to block->last->next
