[Buildroot] libpthread compile error

[Vince]

Hi all,

I try to enable NPTL (uClibc 0.9.30) on my MIPS target but can not build
successfully.

Here is the log:
  STRIP -x -R .note -R .comment lib/libutil.a
  LD libutil-0.9.30.so

make: ***

Error 2

It seems the compiler can't find sysdep.h. Any one has ideas about this
error?

Thanks!
Vince
