Subject: perf tests: Adding build test for having ending double slash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pawel Moll reported build issue for having extra slash (/) at the end of
the prefix variable.

  $ make prefix=/usr/local/

    CC       tests/attr.o
  tests/attr.c: In function ‘test__attr’:
  tests/attr.c:168:50: error: expected ‘)’ before ‘;’ token
    snprintf(path_perf, PATH_MAX, "%s/perf", BINDIR);
                                                ^
  tests/attr.c:176:1: error: expected ‘;’ before ‘}’ token
   }
   ^
  tests/attr.c:176:1: error: control reaches end of non-void function [-Werror=return-type]
   }
   ^
  cc1: all warnings being treated as errors

Adding automated test case for this.
