This symbol access get added by gcc due the -pg option. Now the question is
who should provide this symbol? I would assume it is glibc (actually grepping
glibc source tree shows it is in gmon/mcount.c).
I am not sure why you want to use gprof but anyway...
a) do not use gprof on glibc...
b) change the tests to have a mcount symbol...
c) more options here.
