The problem is that you have told Configure to not use any libraries,
but some are needed. Specifically, when Configure ran it should have
suggested a list of libraries something like

  -lnsl -lndbm -lgdbm -ldbm -ldb -ldl -lm -lc -lposix -lcrypt

You should have accepted that default list.

Some folks have found the relevant Configure prompt confusing. Here's
what it says in the current development track​:

  In order to compile perl5 on your machine, a number of libraries are
  usually needed. Include any other special libraries here as well. Say
  "none" for none. The default list is almost always right.

Hope this helps,

Hi. I wanted to attach the output of myconfig and also what happened when I
was running make so that you could see it. Please let me know if I can do
anything! =)

You're obviously missing the math library.
Rerun configure manually, using the right hint file (linux) and check the '-lm'
ld flag is there (it was for me, it should for you).
