Error building cross-gcc libgcc_s.so

[Michael Eager]

I'm getting an error while building cross-GCC for i586 with newlib.  I'm
using the current CVS mainline.

My configuration (cross x86 compiler):
./Source/gcc/configure --with-gcc-version-trigger=./Source/gcc/gcc/version.c
  --host=i686-pc-linux-gnu --prefix=./Install --target=i586-hardhat-linux
  --program-prefix=i586- --enable-cross --enable-languages=c
  --with-headers=/opt/hardhat/devkit/i586-hardhat-linux/include --with-newlib
  --norecursion     

The error occurs while trying to build a shared library version of libgcc_s.so:

./Build/GCC-i586-hardhat-linux-20001228/gcc/xgcc
  -B./Build/GCC-i586-hardhat-linux-20001228/gcc/
  -B./Install/i586-hardhat-linux/bin/
  -B./Install/i586-hardhat-linux/lib/ -isystem 
  ./Install/i586-hardhat-linux/include -O2  -DCROSS_COMPILE -DIN_GCC
  -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem
  ./include  -fPIC -g1  -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc 
  -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.0 -Wl,--version-script=libgcc.map
  -o libgcc_s.so   libgcc/./_muldi3.o libgcc/./_divdi3.o libgcc/./_moddi3.o 
  <lotsa object files>
  -lc                              
./Install/i586-hardhat-linux/bin/ld: cannot open crti.o: No such file or directory 

The specs file contains the following:

	*startfile:
	%{!shared: %{pg:gcrt1.o%s} %{!pg:%{p:gcrt1.o%s}
        %{!p:%{profile:gcrt1.o%s} %{!profile:crt1.o%s}}}}    
	crti.o%s %{!shared:crtbegin.o%s} %{shared:crtbeginS.o%s} 

	*endfile:
	%{!shared:crtend.o%s} %{shared:crtendS.o%s} crtn.o%s    

Since crti.o (or crtn.o) isn't built in the current directory, the 
linker cannot find it. 

Why should crti.o and crtn.o be included in a shared library?
Or in libgcc?

Why is libc also linked in with libgcc?  Since newlib hasn't been
built, there isn't one to link with.

Is there something that I'm doing wrong?
