[PATCH 5/6] libgloss: i386: cygmon-gmon.c: add functions return type

Functions _mcount(), _etext() and _ftext() lack a return type leading
to below GCC errors:

  cygmon-gmon.c:246:1: error: return type defaults to 'int' [-Wimplicit-int]
    246 | _mcount()
        | ^~~~~~~
  cygmon-gmon.c: In function '_mcount':
  cygmon-gmon.c:268:14: error: type defaults to 'int' in declaration of '_etext' [-Wimplicit-int]
    268 |       extern _etext();
        |              ^~~~~~
  cygmon-gmon.c:269:14: error: type defaults to 'int' in declaration of '_ftext' [-Wimplicit-int]
    269 |       extern _ftext();
        |              ^~~~~~

Add the return type to all these functions.
