I'm using the m68k gcc 3.4.0 toolchain to try to build shared libraries
for uClinux 2.4.31.
I managed to get a barebones image compiled, but BINFMT_FLAT is unable
to load init. This is the problem everyone is running into (according to
posts).

My executable (busybox) is younger than lib1.so (uClibc). Which seems to
be what I want.
Has anyone determined if this using a newer toolchain fixes the problem?
It seems that there have been many changes earlier this year in gcc. For
example, Richard Sandiford checked in a patch that does this:
* config/m68k/uclinux.h (STARTFILE_SPEC): Define. Use Scrt1.o
for shared libraries and crt1.o for executables. Use crti.o and
crtbegin.o.
Maybe there's hope yet. Anybody have try the latest toolchains yet?
4.1.2 or so.
