Initialize attributes for new threads with default values when a NULL

pthread_attr_t is provided as argument to pthread_create.

liblgcc_r_pic.a no longer exists.

Put the liblgcc_r.a version of __get_eh_info() and __register_frame_info()
into the shared linuxthreads library to avoid using the incompatible
libgcc.a version.  Shared libraries that use exceptions still represent a
problem if linked before the linuxthreads library.

Compile liblgcc_r.a before the main linuxthreads library to provide
the object files that contains __get_eh_info() and __register_frame_info().

Add minimal wrappers for native thread library functions used by
5.0-CURRENT libc.  The wrappers try to call corresponding functions
in the linuxthreads library after performing argument conversion.

+   __register_frame_info() and __get_eh_info() from libgcc.a are linked

+   the liblgcc_r.a version of those functions to be used.
