Here's how GDB works around this:

https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=gdb/testsuite/boards/local-board.exp;h=6e0448c58a94afc87e23c33359593a89fecd76fe;hb=HEAD#l20

  20 global board
  21 global board_info
  22 # Remove any target variant specifications from the name.
  23 set baseboard [lindex [split $board "/"] 0]
  24 set board_info($baseboard,isremote) 0
