ld bug with -Bsymbolic --noinhibit-exec (

I'm developing on LinuxPPC R5, with egcs-1.1.2-12c and
binutils- installed.  I'm running into a problem with
using the -Bsymbolic flag.  Building a shared library which references
global symbols that are not found in it, we usually use the
--noinhibit-exec flag so that shared library builds even without those
symbols being bound.

The build command looks like this:

    gcc -shared -Wl,-v -Wl,-Bsymbolic -Wl,--noinhibit-exec -o \
     /ax/axexec/axdata/axshlib/libaxel.so -L/ax/axexec/axdata/axshlib \
     -L/ax/axobj/axdata/rts elimports.o elexports.o \

Without the -Bsymbolic flag, the shared library builds fine.  With the
flag, however, it spits out the following errors (which are expected):

GNU ld version 2.9.4 (with BFD 990418)
/ax/axobj/axdata/rts/axel.o: In function `ElfInstallLibModules':
/ax/axobj/axdata/rts/axel.o(.text+0x38): undefined reference to `ElfInstallModule'
/ax/axobj/axdata/rts/axel.o(.text+0x48): undefined reference to `ElfInstallModule'
/ax/axobj/axdata/rts/axel.o(.text+0x58): undefined reference to `ElfInstallModule'
/ax/axobj/axdata/rts/axel.o: In function `ELElfMacroId':
/ax/axobj/axdata/rts/axel.o(.text+0xc0): undefined reference to `ElfGetModuleStartInd'

On other platforms (i.e., Intel, Alpha), we also see these errors, but
because of the --noinhibit-exec flag, the shared library is correctly
built anyway.  But on PPC, ld returns with 1 exit status, and the shared
library is not built.  Not using -Bsymbolic is not an option.
