[patch] Remove __shtab from libgcc

The patch below removes __shtab from libgcc2.

It follows discussion of data exported from libgcc, and Jim Wilson's
conclusion in http://gcc.gnu.org/ml/gcc-patches/2000-10/msg01069.html
that "__shtab should definitely be dropped."

Trusting his opinion, I've made the (almost trivial) patch below
against the current sources as of earlier today.

To test it, I applied that patch to sources (slightly hacked from)
current as of 2000-10-10 (the Makefile.in patch needed a bit of
tweaking to back-port), and built that targetting mips-elf (from
sparc-solaris).  I then hand-inspected libgcc.a to verify that __shtab
was gone.  It was.  8-)


patch applies in egcs/gcc, changelog below.
