[Buildroot] wanna compile busybox and uclib with self modified code, please help

[hacklinux]

Dear 
thomas:
i got buildroot-2013.08.1 package and created the local.mk file, the content of the file is as follow:
BUSYBOX_OVERRIDE_SRCDIR = /home/wangk/busybox-1.21.1UCLIBC_OVERRIDE_SRCDIR = /home/wangk/uClibc-0.9.33.2
when i tried the make cmd the compile error occured which is as follow:
ROSS_DIRECTORY_STRUCTURE  -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition  -isystem ./include   -fpic -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector   -fpic -I. -I. -I../.././gcc -I../../../libgcc -I../../../libgcc/. -I../../../libgcc/../gcc -I../../../libgcc/../include  -DHAVE_CC_TLS  -DUSE_TLS -o _gcov_execv.o -MT _gcov_execv.o -MD -MP -MF _gcov_execv.dep -DL_gcov_execv -c ../../../libgcc/libgcov.c../../../libgcc/generic-morestack-thread.c:41:21: fatal error: pthread.h: No such file or directorycompilation terminated.make[2]: *** [generic-morestack-thread.o] Error 1make[2]: *** Waiting for unfinished jobs....make[2]: Leaving directory `/home/wangk/buildroot-2013.08.1/output/build/host-gcc-intermediate-4.7.3/build/i686-buildroot-linux-uclibc/libgcc'make[1]: *** [all-target-libgcc] Error 2make[1]: Leaving directory `/home/wangk/buildroot-2013.08.1/output/build/host-gcc-intermediate-4.7.3/build'make: *** [/home/wangk/buildroot-2013.08.1/output/build/host-gcc-intermediate-4.7.3/.stamp_built] Error 2
i knew the reason for this error is miss of pthread.h, but how should i config the busybox to solve the problem.
Best regards.
