warnings.m4: provide a means to specify the program to compile. * m4/warnings.m4 (gl_COMPILER_OPTION_IF): New, extracted from (gl_WARN_ADD): here. Use gl_AS_VAR_APPEND. Support an argument to specify the program to compile. (gl_WARN_ADD): Accept an argument to specify the program to compile. AC_SUBST the WARN_CFLAGS when they are used. * modules/warnings (configure.ac): Don't AC_SUBST WARN_CFLAGS, leave this to gl_WARN_ADD.
