On my box sysfs in defined in libc.0 which is a link to the current version of libc.
Which is where you'd expect it to be....
try to find where sysfs is located:
look for the entry point:
sysfs | 0|sdef |code |$CODE$
If all else fails then link against libc.a as the very last step in the link statement.
Assuming that nm shows it to be in there. Your compiler does support sysfs ie., it's in the man pages?

sysfs
sysfs(2) System Calls sysfs(2)NAME
sysfs - get file system type information
SYNOPSIS
#include <sys/fstyp.h>
#include <sys/fsid.h>
int sysfs(int opcode, const char *fsname);
int sysfs(int opcode, int fs_index, char *buf);
int sysfs(int opcode);
DESCRIPTION
The sysfs() function returns information about the file system types configured in the system. The number of arguments accepted by
sysfs() depends on the opcode argument, which can take the following values:
GETFSIND Translate fsname, a null-terminated file-system type identifier, into a file-system type index.
GETFSTYP Translate fs_index, a file-system type index, into a null-terminated file-system type identifier and write it into the buffer
pointed to by buf, which must be at least of size FSTYPSZ as defined in <sys/fstyp.h>.
GETNFSTYP Return the total number of file system types configured in the system.
RETURN VALUES
Upon successful completion, the value returned depends upon the opcode argument as follows:
GETFSIND the file-system type index
GETFSTYP 0
GETNFSTYP the number of file system types configured
Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The sysfs() function will fail if:
EFAULT The buf or fsname argument points to an illegal address.
EINVAL The fsname argument points to an invalid file-system identifier; the fs_index argument is 0 or invalid; or the opcode argument is
invalid.
