* lib/pascal.exp (gpc_compile): Rename dest arg to destfile.

* lib/pascal.exp (gpc_compile): Rename dest arg to destfile.

The "dest" parameter to fpc_compile/gpc_compile is the name of
compilation destination file, not a board name.

This patch fixes this by using names consistent with
lib/future.exp:gdb_default_target_compile.
