[PATCH] Make libgcc.a symbols .hidden (fix for non-GNU make)

Thank you for looking at this problem.  I can report that with your
proposed patch it now reports this instead:

make: don't know how to make libgcc/./_muldi3.oS. Stop

Here is the exact line in the built Makefile, $objdir/gcc/libgcc.mk,
that still uses a GNU make feature (with your proposed patch):

libgcc/./%.oS: libgcc/./%.o

I am sorry I wasn't completely clear on what GNU make feature you
introduced, here is the exact quote from the GNU make info file:

   * Pattern rules using `%'.  This has been implemented in several
     versions of `make' [but not the baseline BSD 4.2 make -LJR].
     We're not sure who invented it first, but it's been spread around
     a bit.  *Note Defining and Redefining Pattern Rules: Pattern
     Rules.

I tried a few obvious tricks to convert the above rule to work with
BSD make without success.
