  Configure: Fix check for --target support in stage0 CC
  
  The check FP_PROG_CC_LINKER_TARGET used $CC unconditionally to check for
  --target support. However this fails for the stage0 config where the C
  compiler used is not $CC but $CC_STAGE0.
  
  Since we already pass the compiler under test into the macro I simply
  changed it to use that instead.
  
  Fixes #26999
