Makefile - how to fix libc dependency?

I want to statically link Tk into my code. I am running into trouble due to dependencies. The modification I made to my Makefile is:

TK_LIBS_64 = \
    -L/usr/X11R6/lib64 \
    -lX11 \
    -lXss \
    -lXext \
    -L/usr/X11R6/lib64 \
    -lXft \
    -lX11 \
    -lfontconfig \
    -lfreetype \
    -lxmlparse \
    -lexpat \
    -L/usr/X11R6/lib64 \
    -lXrender  \
    -lpthread \
    -ldl \
    -lpthread \
    -lieee \
    -lm

LIBS64 = \
    -L$(TCL_ROOT)/lib/ -ltk8.5 \
    $(TK_LIBS_64)

I get the following error on compilation:

The undefined references are either in libc.a or libc_p.a and adding them to the dependencies does not help. Since the undefined references are system calls I think I am missing something basic here. I would be obliged if someone can point out the mistake.

use -pthread instead of -lpthread
