You should be looking in glibc, not GCC -- it seems to be defined in strlen.c -- here's a link to strlen.c for glibc version 2.7... And here is a link to the glibc SVN repository online for strlen.c.

The reason you should be looking at glibc and not gcc is:

The GNU C library is used as the C library in the GNU system and most systems with the Linux kernel.
