"ld: cannot find -lgcc_eh"

[Robert P. J. Day]

  yes, i know this has a known patch.  for my bleeding edge combo of
toolchain parts, the inline patch fixed the last problem (at least,
that's not where the build blew up this time.)

  now, it's (big snip coming here, 77000 lines in):

  .../home/rob/ct/crosstool-0.28-rc37/build/sh3eb-unknown-linux-gnu/gcc-4.0-20041128-glibc-20041204/build-glibc/elf/ld.so
-lgcc -lgcc_eh

 /home/rob/ct/results/sh3eb-unknown-linux-gnu/gcc-4.0-20041128-glibc-20041204/lib/gcc/sh3eb-unknown-linux-gnu/4.0.0/../../../../sh3eb-unknown-linux-gnu/bin/ld:
cannot find -lgcc_eh


  and, sure enough, we have
patches/glibc-2.3.3/glibc-2.3.3-libeh-kludge.patch

which appears to address that problem beautifully.  well, at least it
does with glibc-2.3.3, the patch being fairly strightforward -- get
rid of the library reference on that line in Makeconfig:

  but Makeconfig in glibc-20041204 has a more complicated structure at
that point:

=====

ifndef gnulib
ifneq ($(have-as-needed),yes)
 libgcc_eh := -lgcc_eh
else
 libgcc_eh := -Wl,--as-needed -lgcc_s$(libgcc_s_suffix)
-Wl,--no-as-needed
endif
ifneq ($(have-cc-with-libunwind),yes)
 gnulib := -lgcc $(libgcc_eh)
 static-gnulib := -lgcc -lgcc_eh
else
 gnulib := -lgcc $(libgcc_eh) -lunwind
 static-gnulib := -lgcc -lgcc_eh -lunwind
endif
endif

=====

  i'm open to suggestions as to the equivalent patch in *this*
Makeconfig file, and i'll give it a shot before i head out for lunch.
