Re: Issues cross compiling NSS for arm undefined reference to pthread_atfork

EDIT: I found it in <sysroot>/lib/libpthread-2.8.so, and it does contain
a reference to that function:

"readelf -Ws libpthread-2.8.so  | grep atfork":

   62: 00000000     0 FUNC    GLOBAL DEFAULT  UND
__register_atfork@GLIBC_2.4 (4)
   218: 0000b46c    24 FUNC    GLOBAL DEFAULT   12 pthread_atfork@GLIBC_2.4
   366: 00000000     0 FILE    LOCAL  DEFAULT  ABS old_pthread_atfork.c
   764: 0000b46c    24 FUNC    LOCAL  DEFAULT   12 __dyn_pthread_atfork
  1063: 0000b46c    24 FUNC    GLOBAL DEFAULT   12 pthread_atfork@GLIBC_2.4
  1202: 00000000     0 FUNC    GLOBAL DEFAULT  UND
__register_atfork@@GLIBC_2.4

I'm not really sure where to go from here.
