With the minimum gcc version raised to 8.1, all supported compilers now understand the -fsanitize-coverage=trace-pc option, and there is no longer a need for the separate compiler plugin. Since only gcc-5 was able to use the plugin for several year now, it was already likely unused. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
