[PATCH] Fix gdb crash due to SIGPIPE when the compile command fails

[Bernd Edlinger <bernd.edlinger@hotmail.de>]

Due to the SIGPIPE the gdb process is killed here, which is
not helpful.

2021-06-02  Bernd Edlinger  <bernd.edlinger@hotmail.de>

	* compile/compile.c (compile_to_object): Ignore SIGPIPE before calling
	the plugin.
