As far as I can see this comes from a file called gmon.o which is only
built for selected targets (arm-elf not being one of these targets (in fact
it isn't built for any arm target);  look for "gmon" in gcc/config.gcc to
work out which targets it is supported on).     As this is file is in a
list of "extra" files like crt1.o, crti.o, etc.  I suspect that it isn't
included in any library but rather just added by gcc onto the list of files
to be linked to a program if it is required (and supported for that target).
